초록

A laser scanner utilizing a computer-generated hologram(CGH) as beam deflector is reported. The CGH optical element has been used mainly for under-filled scanning. Here, a CGH optical element for overfilled scanning is proposed. It can achieve, under the same limitation of fabrication accuracy, better resolution and longer scan length than those for under-filled scanning. Measured scanning characteristics of the laser scanner show the scan length of 40 cm and the beam diameter of 100\ulcorner, where the designed minimum distance between the lines of CGH is 8\ulcorner.
