Product Details
This structured‑light projection engine serves as the "heart" of high‑performance 3D AOI cameras, acting as the core power source for accurate object‑profile reconstruction in 3D inspection for electronics manufacturing. As a critical component for projecting coded‑light patterns, it directly determines inspection accuracy, anti‑interference performance and operating speed of the entire 3D AOI system, laying a solid foundation for high‑precision defect detection.
Equipped with advanced DLP display technology, the engine projects high‑brightness, high‑contrast coded patterns (multi‑frequency fringes, Gray codes or random dot matrices) with ultra‑fine pixel pitch for clear and controllable imaging details. The innovative blue‑light projection design effectively suppresses reflection interference from high‑glare surfaces such as solder joints and metal components. Combined with adaptive pattern modulation technology, stable and sharp imaging is achieved even for high‑density PCBs or shadowed areas.

Applications:
- 3D AOI, 3D SPI, high‑precision 3D scanning, etc.
