The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A focal plane array (FPA) having an array of pixels, wherein each pixel comprises:
a plurality of radiation detectors, each detector having a collection region, the detectors’ collection regions overlapping within each said pixel;
a lens element that concentrates incident radiation into a focal region that is covered by a union of the detectors’ collection regions; and
a plurality of switch elements connected to respective detectors, each said switch element being switchable between a first state for transmitting a signal received from its corresponding detector to an output and a second state for blocking transmittal of the signal for a de-selected detector,
wherein when the switch element is in the second state the de-selected detector floats to a photovoltage and re-emits some of its accumulated photo charge into the neighboring detectors within the pixel.
2. The FPA of claim 1, wherein each pixel further comprises:
a summing circuit that sums the transmitted signals to form a pixel signal.
3. The FPA of claim 1, wherein the switch elements for each pixel are switched in accordance with a map of bad radiation detectors such that the bad radiation detectors are de-selected.
4. The FPA of claim 3, wherein each switch element comprises:
a switch that is switchable between said first and second states;
in-pixel memory for storing a map value for the corresponding sub-pixel detector; and
a de-select address circuit that is responsive to the map value to control said switch.
5. The FPA of claim 1, wherein the shape of the lens element is independent of the selection or de-selection of any of said detectors with each said pixel.
6. The FPA of claim 5, wherein the lens element concentrates the incident radiation into substantially uniform focal regions across the plurality of detectors in each pixel.
7. The FPA of claim 1, wherein the focal region does not lie completely within the collection region of any one of the radiation detectors within each said pixel.
8. The FPA of claim 1, wherein the number of detectors in said array exceeds the number of lens elements in said array.
9. The FPA of claim 1, wherein said detectors are off-center of the focal region for the respective pixels.
10. A focal plane array (FPA), comprising:
a pixilated detector array including a plurality of radiation detectors in each pixel, said detectors having overlapping collection regions with each pixel;
a microlens array including lens elements that concentrate incident radiation into respective focal regions that are covered by a union of the detectors’ overlapping collection regions within each pixel;
and a ROIC that includes for each pixel:
a summing circuit; and
a plurality of switch elements connected between respective detectors and the summing circuit, each said switch element being switchable between a first state for transmitting a signal received from its corresponding detector to the summing circuit and a second state for blocking transmittal of the signal while allowing the de-selected detector to float to a photovoltage and re-emit some of its accumulated photo charge into the neighboring detectors within the pixel.
11. The FPA of claim 10, wherein the switch elements for each pixel are switched in accordance with a map of bad radiation detectors such that the bad radiation detectors are de-selected.
12. The FPA of claim 11, wherein each switch element comprises:
a switch that is switchable between said first and second states;
in-pixel memory for storing a map value for the corresponding sub-pixel detector; and
a de-select address circuit that is responsive to the map value to control said switch.
13. The FPA of claim 10, wherein the shape of the lens elements is independent of the selection or de-selection of any of said detectors with each said pixel.
14. The FPA of claim 13, wherein the lens elements concentrate the incident radiation into substantially uniform focal regions across the detector array.
15. A method for operating a focal plane array (FPA), comprising:
providing a pixilated FPA having a plurality of detectors per pixel, each said detector having a collection region;
directing radiation incident into respective focal regions that are covered by a union of the detectors’ collection regions with each pixel, wherein the detectors’ collection regions overlap within each pixel;
de-selecting bad detectors;
allowing the bad detectors to float to a photovoltage to re-emit accumulated charge to neighboring detectors within the pixel;
combining output signals from the remaining detectors within each pixel to form pixel output signals; and
reading out the pixel output signals to form an output image.
16. The method of claim 15, further comprising:
storing a map of bad detectors in said FPA, and de-selecting the bad detectors in accordance with the map.
17. The method of claim 16, further comprising:
testing the FPA to determine defective detectors in the FPA; and updating the map stored in the FPA.
18. The method of claim 15, wherein the incident radiation is directed into the respective focal regions independent of the de-selecting of bad detectors.
