Dynamical Effects of the Rhombic Drive for Miniature Cooling Engines
Infrared systems for nocturnal surveillance have been the subject of keen military interest and research for a number of years. Excellent lightweight, low-power devices with remarkable resolution are now available. They are characterized by operation within the temperature range 20° to 80°K and with a cryogenic cooling requirement of about 0.25 W at 20°K to 1 W at 80°K.
