    Abstract: An imaging system and method that captures compressive sensing (CS) measurements of a received light stream, and also obtains samples of background light level (BGLL). The BGLL samples may be used to compensate the CS measurements for variations in the BGLL. The system includes: a light modulator to spatially modulate the received light stream with spatial patterns, and a lens to concentrate the modulated light stream onto a light detector. The samples of BGLL may be obtained in various ways: (a) injecting calibration patterns among the spatial patterns; (b) measuring complementary light reflected by digital micromirrors onto a secondary output path; (c) separating and measuring a portion of light from the optical input path; (d) low-pass filtering the CS measurements; and (e) employing a light power meter with its own separate input path. Also, the CS measurements may be high-pass filtered to attenuate background light variation.

    Abstract: A compressive imaging system including a light modulator, a light sensing device and a TIR prism. The TIR prism is configured to receive an incident light beam, to provide the incident light beam to the light modulator, to receive a modulated light beam MLB from the light modulator, and to direct the modulated light beam onto a sensing path. The light sensing device receives the modulated light beam (or at least a portion of the modulated light beam) and generates an electrical signal that represents intensity of the modulated light beam (or the “at least a portion” of the modulated light beam). The TIR prism may reduce a distance required to separate the incident light beam from the modulated light beam.

    Abstract: Mechanisms for increasing the rate of acquisition of compressed/encoded image representations are disclosed. An imaging system may deliver subsets of a modulated light stream onto respective light sensing devices. The light sensing devices may be sampled in parallel. Samples from each light sensing device may be used to construct a respective sub-image of a final image. The parallelism allows compressed images to be acquired at a higher rate. The number of light sensing devices and/or the number of pixels per image may be selected to achieve a target image acquisition rate. In another embodiment, spatial portions of the incident light stream are separated and delivered to separate light modulators. In yet another embodiment, the incident light stream is split into a plurality of beams, each of which retains the image present in the incident light stream and is delivered to a separate light modulator.

    Abstract: A system and method for conserving power in compressive imaging. An optical subsystem separates an incident light stream into a primary light stream and a secondary light stream. The primary light stream is modulated with a sequence of spatial patterns by a light modulator. The modulated light stream is sensed by a first light sensing device. The secondary light stream is sensed by a second light sensing device. The signal(s) produced by the second light sensing device may be monitored to determine when to turn on power to the light modulator. Thus, the light modulator may remain off when not needed. In an alternative implementation, a light sensing device is used to sense the light reflected from the light modulator in its power-off state. The signal(s) produced by that light sensing device may be monitored to determine when to turn on power to the light modulator.
