Paper Abstract

Under sponsorship of the Naval Air Systems Command, an electronically variable neutral density filter for automatic background compensation has been successfully developed by the Naval Missile Center and Sandia Laboratories for use with vidicons. The same filter can also be used with film cameras, and with minor modifications, it can operate as a microsecond duration electro-optical shutter in infrared sys-tems. This article describes the filter operating principle, test configuration, and test results.
