Abstract: A surface measuring device includes a rotary platform, a shifting lever, a measuring module, and a control module. The rotary platform carries an object under test and rotates the object under test at a rotating speed. The shifting lever is above the rotary platform. The measuring module disposed on the shifting lever moves to measurement positions on the shifting lever and performs a surface height measurement at a sampling frequency to sampling points on a surface of the object under test when located at one measurement position. The control module selectively adjusts the rotational speed for the rotary platform or the sampling frequency for the measuring module according to the measurement position of the measuring module on the shifting lever in order to fit a distance between the sampling points on at least one part of the surface of the object under test to a sampling rule.

Abstract: A detection system for a multilayer film is provided. The detection system for a multilayer film includes a light source device, a first image capture device, a second image capture device and an image processing device. The light source device projects a pair of parallel incident light to a transparent multilayer film obliquely. The pair of parallel incident light is projected onto the transparent multilayer film for producing and enabling a forward scattered light and a back scattered light to be projected therefrom. The first image capture device captures the back scattered light to produce a first image. The second image capture device captures the forward scattered light to produce a second image. The image processing device is coupled to the first image capture device and the second image capture device. The image processing device is used to compares and detect the differences between the second image and the first image.

Abstract: A three-dimensional measurement system includes a projector, an image sensor, an image analyzing module and a measurement module. The projector provides a structured light pattern. The image sensor captures an object image of an object on which the structured light pattern is projected. The image analyzing module analyzes the object image to obtain a space coding image and a phase coding image according to gray level distribution of the object image. The measurement module calculates phase information of each of coordinate points in the phase coding image, calculates compensation information of a coordinate position, corresponding to a coordinate position of a point of discontinuity, in the space coding image, compensates the phase information of the point of discontinuity in the phase coding image by the compensation information, and calculates height information of the object according to the phase information of each of the coordinate points.
