Abstract: An active optical compressive sensing system includes an optical source to generate light for illuminating a target and a pattern generator to generate a pattern. A pattern controller controls an operation of the pattern generator to cause generation of a desired pattern. The pattern is a spatial filtering pattern that enables data compression by generating sparse scattered data. Applying the pattern allows a logarithmic resource scaling.

Abstract: An imaging system includes an imaging platform that has a first aperture and a second aperture that are separated by a separation distance in a predefined direction. The imaging system includes a transmitter device coupled to the first aperture that transmits an optical signal via the first aperture in a first direction perpendicular to the predefined direction. A first receiver of the imaging system receives, via the first aperture, a first reflected signal in the first direction from a target object at a range distance. A second receiver of the imaging system receives, via the second aperture, a second reflected signal in the first direction from the target object. A processor unit of the imaging system determines a phase difference between the first and second reflected signals. The processor unit also determines an estimate of a height of the target object based on the phase difference and the range distance.
