- Abstract
- This work was undertaken to determine the benefits of a true monochromatic optical system for variable-density recording in the ultraviolet region. A full quartz optical system consisting of both spherical and cylindrical lenses was used, having a reduction of 10-1 from the light-valve spacing. The reduction in lens distortion and improvement in general image quality is reported along with intermodulation tests on the system, which uses an automatic air-controlled mercury-vapor lamp system.
