Abstract

An exemplary lensless compressive imaging device may include a micro mirror array having a plurality of mirror elements that are individually controllable for selectively directing light reflecting from the micro mirror array. A detector detects light reflected from at least one of the mirror elements. A processor provides compressive image information based on the detected light.

Claims

a micro mirror array including a plurality of mirror elements that are individually controllable for selectively directing light reflecting from the micro minor array;

a detector that is configured to detect light reflected from at least one of the minor elements; and

a processor that is configured to provide compressive image information based on the detected light.

2. The device of claim 1, wherein the detected light comprises visible light.

3. The device of claim 1, wherein the detected light comprises infrared light.

4. The device of claim 1, comprising an infrared detector configured for detecting infrared light and wherein the detector is configured for detecting visible light.

5. The device of claim 4, wherein the processor is configured to provide the compressive image information based on detected light from each of the detectors, respectively.

6. The device of claim 4, wherein a first set of the mirror elements reflect visible light toward the detector and a second set of the mirror elements reflect infrared light toward the infrared detector.

7. The device of claim 1, wherein at least one of the detector or the micro minor array is moveable relative to the other for selectively varying a distance between the micro minor array and the detector.

8. The device of claim 1, wherein orientations of the minor elements are controlled according to a basis and the basis is selectively varied.

9. A lensless compressive image acquisition method comprising the steps of:
