Abstract
A 360 degree infrared surveillance system comprising a scanning head rota on a turntable having optics and IR detectors in a vertical linear array, amplifiers for each detector and light emitting diodes for each respective detector/amplifier channel. The light from the LED's is imaged onto photodetectors whose output is amplified and fed to a corresponding LED. An optical rotator causes the image of their light to rotate. A lens images this light onto photodetectors located on the projector turntable, rotating synchronously with the scanner head. The photodetector current is amplified and fed to a linear array of LED's and imaged onto a cylindrical screen for display.
