Description
To address the Armys need for tunable laser line rejection transmission (notch) filters in the longwave infrared (LWIR) region, Physical Optics Corporation (POC) proposes to develop a new polarization insensitive Longwave Infrared Electrically Tunable Laser Line Rejection Filter (ETIRE) based on fast (>60 Hz) electrical tuning of the reflection peak of cholesteric liquid crystal (CHLC) to reject the undesired laser line wavelengths without any mechanical movement. The proposed design allows ETIRE to efficiently block laser radiation (>90% rejection at the notch), while transmitting ambient light (>90%). The innovative ETIRE design enables filter linewidth of
