Abstract

The Photoelectric Rotating Slit Elevation and Azimuth Sensor (perseas) measures the azimuth and elevation of the line of sight to a target reflecting or emitting radiation in the 0.4- to 1.1-μ portion of the spectrum. Angular field of view is 360° in azimuth and 30° in elevation. Eight stationary lenses are used with rotating fiber-optics slits and silicon photodiode detectors to produce electrical pulses which are time related to target angular coordinates. Data rate is one line-of-sight measurement per 2.5 msec. Accuracy is better than 1 mrad.
