Optical imaging measurement is currently one of the relatively advanced precision and high – efficiency measurement methods. Its working principle is as follows: The workpiece to be measured (placed on the workbench) is illuminated by LED surface light or bottom light (inside the base). After that, the image is captured through a zoom objective lens and a color CCD camera (inside the housing), and then transmitted via a video terminal to a dedicated image acquisition card for the image, and finally displayed on the computer screen. The optical scale is moved in the X and Y directions by the workbench, and through computer data processing, the measurement work is completed.
It is mainly composed of four major parts: the structural body, the imaging system, the control box, and the dedicated measurement software.
The structural body includes: the base, the column, the XY moving workbench, the XY moving mechanism, and the Z – axis transmission mechanism.
The imaging system includes: a zoom objective lens, a CCD camera, a transmission, reflection, and light source control system.
The control system includes: a controller/data connection cable.
The professional measurement software includes: a software instruction manual, an encryption lock, and an image acquisition card.
