| Popis: | 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- tol.1-micro portion of the spectrum. Angular field of view is 360 degrees in azimuth and 30 degrees 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. |
