Structured Light Projection Optomechanical Assembly
The structured-light projection device, called a mimeograph in the source, is the heart of a high-performance 3D AOI camera and the core source for precise reconstruction of object shapes in electronics manufacturing inspection. As the component projecting coded patterns, it directly determines the 3D AOI system's accuracy, interference resistance, and operating speed, supporting precision defect detection. Advanced DLP display technology projects bright, high-contrast patterns such as multifrequency fringes, Gray codes, and random dot arrays, with very fine pixel spacing and clear, controllable detail. An innovative blue-light design suppresses reflective interference from shiny solder joints and metal components. Adaptive pattern modulation maintains stable, clear imaging even on dense PCBs or in shadowed regions, resolving inspection challenges in complex scenes.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
