Patent ID: CN201210580743.1

Disc and its production methods, structured light illumination pattern generation means

Description: The disc; a structure for implementing lighting disc, the disc area are divided into nine sectors; at the edge of the disk is provided with a nine pore complexes trigger signal generated imaging There is a grill on each fan-shaped area, were in turn divided into a grid of nine, including three first grill grid group, the second group and the third grid grill set; the first grid group Each grating tilt angle is negative 120 degrees; the second group of each of the grid grating tilt angle of 0 degrees; the third group each of the grid grating tilt angle is 120 °; in each lattice gate grid is divided into three parallel, when the image grid and the same group, each grill stripes laterally offset one third cycle. In addition, it also provides a production method and structure of the optical disk of the illumination pattern generating means. The disc and its production methods, structured light illumination pattern generating device, easy operation, and imaging fast, controlled rotation of the disc without expensive precision instruments, reducing the cost.
