3.1.2.1 Description
The optics head module, sitting on the gantry module, performs the image taking function, and
based on which, the expected inspection results are given.
The optics head module is split up into 2 parts, the DLP Projector Module and the Imaging Module.
The DLP projects fringes with different widths and frequencies onto the board, and the imaging
module grabs pictures and the system re-construct the 3D object based on those images taken.
