Liquid Crystal Displays for the Evaluation of CO2 Lasers

摘要

Experimental thin membrane type displays of cholesteric liquid crystals for the display of infrared laser beams have been developed. Both experiment and theoretical analysis demonstrates that there is a trade-off between rise time, decay time, resolution and sensitivity, with membrane thickness and surface cooling the principal limiting parameters. A new type of display in which the liquid crystal is deposited on a semiinfinite block of material shows promise as a suitable display for applications in which the incident power is a few watts/sq cm or larger.
