Abstract

The Computer Imaging Branch of the Corporate Manufacturing Center at Texas Instruments has designed and built high-speed high-resolution laser writing systems since 1982. These systems have a range of effective pixel size from 10 down to 0.5 μm, with writing rates as high as 100 Mpixels/s. Although originally designed for circuit board and photomask application, these systems are well suited for the plotting of computer-generated holograms. Recently, an internal program was initiated to investigate the application of computer-generated holograms for the testing of diamond point turned aspheric optics. This presentation focuses on the description of our laser writers, the methods by which the holograms are computed from CO­DEV (TM) polynomial representations, and the results using the binary holograms for testing as-pheres.
