Features included in i-Solution DT-L/ DT/ DT-M iSolution DT-L is the program focused on core material science applications.iSolution DT has all features for various science and inspection applications.iSolution DT-M is the motorized stage control application version having all features of iSolution DT.It has many new developed functions alsoInclude:Live Measurement and Overlay SettingsUsers can perform measurements on the live preview image, using the crosshair or grid masks to center and count. The grid masks include calibration data. Calibration marker (scale bar) can be placed on the live preview image. The marker (scale bar) can also be burned on each captured image automatically. Anystandard file format image can be chosen to see it above live preview image.Calibration (Auto, Manual)All measurements start with an accurate calibration. Auto, Semi-Auto calibration functions allow the software to calculate the pixels-per-unit value automatically. Only setting the unit for the calibration scale and the distance between the scale marks is needed. This feature greatly improves the accuracy and repetition of measurements. Manual calibrations are easily added and saved for recall from a drop down menu. All calibrations can be saved as files, which let the calibration be retrieved by simply opening the saved files later.Calibration can be protected by password option. Two password options, one in calibration menu itself and the other in camera resolution option, protect calibration by unexpected change. A scale bar can be permanently added to each image. Scale bar properties for color, size and text are simple to optimize for any image background.Z-Axis Extended Focus Imaging (EFI), with displacement compensation for stereo microscopesSamples with curves or of varying heights are difficult to bring into focus under highly magnified conditions. And more a stereomicroscope takes images with tilting due to its own structural characteristics. Thus, each image is out of its supposed position when you move microscope to the Z-axis getting the right focus. Our displacement compensation function allows you to rearrange these images automatically and manually.Software can combine a stack of images sequentially captured at different levels of focus and combine them into a single in-focus image. You can count on our software not to leave any trace of the composites.3D Visualization. . . clearly view complex structuresA Three-dimensional picture can be created from any image. The 3-D presentation is based upon intensity values of the image and can be displayed as a normal or wire frame image. Z axis information can easily be adjusted to optimize the 3-D effect. To better visualize an image in 3-D, software offers full 360 degrees of rotation on X-Y-Z axis. A 3D image can then saved in JPG, TIF or BMP format.Image Stitching. . . create a mosaic of the “Big Picture”With our software, you can create auto and manual composites of continuously captured images in order to minimize the reduction in the field-of-view that typically comes with increased magnification. Combined images are automatically corrected for brightness without leaving any stitching mark. Live Image Comparison. . . for fast inspection and size verificationFor QA testing or quick go/no-go inspections any stored image can be used as a reference image onto which the live preview image is projected.Time Lapse Capture and Movie File Production. . . Import into Power PointSoftware features a Time Lapse Capture function that supports TIF, BMP and JPG file formats. The Time Lapse Capture function also includes an Auto Save feature byyyyy/mm/dd/hour/minute/second. You can save video movie recordings in AVI, MPG, MPEG, and MOV formats.Combine Image Planes - Fluorescence ImagingMerge and pseudo color monochrome images into a single RGB composite.Advanced - Fluorescence Image mergeFluorescence merging function allows several images to one composite image.There is rich list of pre-defined dyes already.One can choose desired emission wavelength in nanometers also and then correspondent color is calculated automaticallyExport Into Excel® - with one mouse clickA single mouse click exports the original image with measurement, calibration, annotation overlay, measurement data, statistics, and chart.Manual Measurement Tools - Including Various Perpendicular DistanceSoftware’s versatile manual measurement features include tools for measuring lengths, areas, and angles and can even auto detect an object's outline and then make specified measurements. The software is equipped with a wide choice of powerful measurement tools including 3-point circle functionality, Npoint circle measurement functionality, parallel line distance measurement, perpendicular distance measurement and object distance measurement. In addition, a zoom-in window can be used to determine the accurate measuring point of an object.Once you've measured a specimen you can easily export all of the images, measurement data and statistics to an Excel® file. With i-Solution DT, comprehensive statistics and data are just one effortless mouse click away.Line ProfilingSingle, multiple, parallel and polyline commands provide Gray/Red/Green/Blue intensity values for specific lines within an image. The profile data of each pixel on the line can be exported to MS Excel. Auto TraceUsing an automatic edge detection algorithm, our software will perform an auto trace measurement function around a closed object. This function greatly increases accuracy and saves time when makingmeasurements of complex shapes.Image ProcessingManual Brightness, Contrast, Gamma, Background Subtraction, Shading Correction, Histogram, Clone, Crop, AOI, Resize, Rotate, Split, Merge Monochrome series into RGB Color, Combine different exposure Images for highlight reduction, Image Mode Change, Grayscale, RGB, HSB, YUV Pseudo Color view, Full range of enhancement and morphology filters 8bit and 16bit per channel Manual MeasurementsPoint Count, Straight Line, Circle by radius, Circle by N points, Circle by diameter, Circle by 3 points, rectangle, polygon, polyline, splice lines from a common point, auto trace, angle parallel lines, perpendicular width, perpendicular from common line, angle between 2 lines, distance, perpendicular distance.Shading CorrectionThe edge parts of captured image by low magnification have background shading frequently, which can be removed by the shading correction function. The color of the original image remains the same though. A standard image is acquired from a blank space on the slide glass, or from an out of focus image in a metallurgical specimen. Such a standard image is used to correct the background shading of all other captured images.AnnotationLine, arrow, polyline, spline, rectangle, ellipse, textRegion of Interest- ROI. . . . with unique add/subtract capabilityRectangle, arbitrary rectangle, circle, arbitrary ellipse, polyline, spline, magic wand ROI itself can be saved to work with other images. The saved ROI can be placed on the exact same location of other images.View and Zoom ImageManual zoom In-Out, User Defined, Fit to Window, 1600% Zoom in Window for Accurate Edge Detect, sizeable context Window to view all open ImagesImage EditingUndo, Redo, Copy, Paste, Paste New, Delete, Delete All, Annotate, Image InformationSave OptionsTXT File Format, image and measurement data together in Proprietary .img File Format for future editing and data collectionSupported Image File Formatsjpg, jpeg, tif, tiff, bmp, gif, pcx, tga, mpg, mpeg, avi, mov, img, rpt, txt and etc.Report GeneratorCreate Report, Insert Image and Data, Insert other OLE ObjectsWindow ViewSplit Horizontal, Split Vertical, Cascade, Tile Horizontal, Tile Vertical, Arrange icons, Dynamic User Interface (UI), Classic, ModernTime Lapse Sequence ControlPlay Forward, Backward, Making Movie File (mpg, avi, mov) with Still Images, Split Single Image from Sequence FileAuto/Manual Thresholding for Count and SizeIntensity and color based thresholding tools for identifying, counting and categorizing objects.Ideal for automatic objects counting and percentage of area measurements.Objects Editing… enhanced measurement accuracy!Target threshold objects can be edited by all measurement parameters or with filters to clean, close, open, dilate, erode, automatic separate and fill holes.Densitometryi-Solution software automatically calculates Optical Density (OD) by absolute and relative figures, semi automatically, or manually based on user configuration.

电子水准仪操作规程
电子水准仪的使用包括：电子水准仪的安置、整平、瞄准、读数四个步骤。

⑴安置：
安置是将仪器安装在可以伸缩的三脚架上并置于两观测点之间。

首先打开三脚架并使高度适中，用目估架顶大致水平并检查脚架是否牢固，然后打开仪器箱，用连接螺旋将水准仪器连接在三脚架上。

⑵整平：
整平是使仪器的视线水平，利用脚螺旋置圆水准气泡居于圆指标圈之中。

调整圆水准气泡，气泡移动的方向与大姆指运动的方向一致，将水准仪整平。

⑶瞄准：
瞄准是用望远镜准确地瞄准目标。

首先是把望远镜对向远处明亮的背景，转动目镜调焦螺旋，使十字丝最清晰。

再松开固定螺旋，旋转望远镜，使照门和准星的连接对准水准尺，最后转动物镜调焦螺旋，使水准尺的清晰地落在十字丝平面上，消除视差，再转动微动螺旋，使水准尺的像靠于十字竖丝的一侧。

⑷读数：
用十字丝，截读水准尺上的读数。

电子水准仪是利用数字图像处理技术读数，读数精确至0.00001mm。

按电子水准仪进行观测，以往测奇数测站为例，一测站的操作程序如下：
⑴首先整平仪器，调节数字水准仪角螺旋，使圆气泡位于指标圆环中央，望远镜绕垂直轴旋转180度，圆气泡仍位于指标圆环中央；
⑵将望远镜照准后视水准标尺，用垂直丝照准条码中央，精确调焦至条码影像清晰，按测量键读数；
⑶显示读数后，旋转望远镜照准前视标尺，用垂直丝照准条码中央，精确调焦至条码影像清晰，按测量键读数；
⑷显示读数后，重新照准前视水准标尺条码中央，按测量键读数；
⑸显示读数后，旋转望远镜照准后视水准标尺条码中央，精确调焦至条码影像清晰，按测量键读数，显示测站成果，测站检核合格迁下一站。
