Coded aperture focal plane array

1. A sensing system, comprising:

a focal plane array having an n×m array of sensing elements, wherein n and m are array element index values, and a single output pixel, wherein the focal plane array comprises part of a readout integrated circuit package;

a mask to select or deselect ones of the sensing elements in the array to form patterns, wherein the mask forms a part of the focal plane array; and

a select module to control the mask select and deselections.

2. The system according to claim 1 , further including an imager to focus light on the focal plane array.

3. The system according to claim 1 , wherein the mask is configured to provide Hadamard mask patterns.

4. The system according to claim 1 , wherein the select module is configured to cycle the mask through the mask patterns.

5. The system according to claim 1 , wherein n=1.

6. The system according to claim 1 , wherein the system provides a hemispherical field of view.

7. The system according to claim 1 , wherein the mask patterns are applied to a region of interest in field of view for the sensing system.

8. The system according to claim 1 , wherein de-selected ones of the sensing elements are tied to a bias to shunt current.

9. The method according to claim 1 , further including applying the mask patterns to a region of interest in field of view for the sensing system.

10. A method, comprising:

employing a focal plane array having an n×m array of sensing elements, wherein n and m are array element index values, and a single output pixel, wherein the focal plane array comprises part of a readout integrated circuit package; and

controlling a mask with a select module to select or deselect ones of the sensing elements in the array to form patterns, wherein the mask forms a part of the focal plane array.

11. The method according to claim 10 , further including controlling the mask with a select module to control the mask select and deselections.

12. The method according to claim 10 , further including employing an imager to focus light on the focal plane array.

13. The method according to claim 10 , wherein focal plane array comprises part of a readout integrated circuit package.

14. The method according to claim 10 , wherein the mask provides Hadamard mask patterns.

15. The method according to claim 10 , further including cycling the mask through the mask patterns.

16. The method according to claim 10 , wherein the system provides a hemispherical field of view.

17. The method according to claim 10 , wherein n=1.

18. A sensing system, comprising:

a means for sensing including a focal plane array having an n×m array of sensing elements, wherein n and m are array element index values, and a single output pixel, wherein the focal plane array comprises part of a readout integrated circuit package; and

a means for selecting or deselecting ones of the sensing elements in the array to form patterns, wherein the mask forms a part of the focal plane array, wherein the means for selecting or deselecting includes a select module to control the mask select and deselections.
