Abstract

A self-contained system embodying the principles of the radiometer, the otheoscope, and the dynamoelectric machine is provided to derive an output of electrical energy from an input of radiant energy, and in particular infra-red energy, from the surrounding environment, and for amplifying that output. The system is suitable for airborne and space as well as terrestrial applications.
