30 March 2001 Optical active pupil based on PDLC
Author Affiliations +
Polymer Dispersed Liquid Crystal (PDLC) is commonly used as active diffuser and optical switches. In this work we propose an optical active pupil by using the PDLC. The aperture size of this device is electronic controlled with highly accuracy and is determined by the diffused region. This device is made of similar way commercial PDLCs, but changes in the thickness of one glass plate, change a flat surface by concave surface. Some experimental results are shown.
