Abstract
An active situational sensor uses a beam steerer to steer a spot-beam onto a conical shape of a fixed mirror oriented along an optical axis to scan a FOR. The sensor may rapidly scan a 360° horizontal FOR with a specified vertical FOR or any portion thereof, move discretely between multiple specific objects per frame, vary the dwell time on an object or compensate for other external factors to tailor the scan to a particular application or changing conditions in real-time. The fixed mirror includes a MEMS MMA that approximates the conical shape of the mirror. The MEMS MMA being configurable to extend the vertical FOR or shape the spot-beam to adjust size, focus or intensity profile or to produce deviations in the wavefront of the spot-beam to compensate for path length differences or atmospheric distortion. The MEMS MMA being configurable to produce and independently steer a plurality of spot-beams of the same or different wavelengths.
