ABSTRACT:
The optical transitions of extrinsicially optically active insoluble materials become optically active and circularly dichroic when in contact with optically negative liquid crystalline materials thereby producing unusual and highly advantageous properties. The circularly dichroic optical properties induced in the extrinsically optically active insoluble materials can be utilized for converting infrared images to visible images.
