Abstract
Methods and apparatus for a dual mode focal plane array having a background module including a first capacitor to integrate a first signal for a first amount of time, wherein the first signal comprises a background signal, and a signal module including a second capacitor to integrate a second signal for a second amount of time, wherein the second signal comprises a signal of interest and the background signal, wherein the first and second capacitors have impedance values in a first ratio, and wherein the first amount of time and the second amount of time define a second ratio corresponding to the first ratio.
Claims20
A system, comprising:
- a background module including a first capacitor to integrate a first signal for a first amount of time, wherein the first signal comprises a background signal;
- and
- a signal module including a second capacitor to integrate a second signal for a second amount of time, wherein the second signal comprises a signal of interest and the background signal, wherein the first and second capacitors have impedance values in a first ratio, and wherein the first amount of time and the second amount of time define a second ratio corresponding to the first ratio.
A method, comprising:
- integrating a first signal for a first amount of time, wherein the first signal comprises a background signal, using a first capacitor;
- and
- integrating a second signal for a second amount of time using a second capacitor, wherein the second signal comprises a signal of interest and the background signal, wherein the first and second capacitors have impedance values in a first ratio, and wherein the first amount of time and the second amount of time define a second ratio corresponding to the first ratio.
A system, comprising:
- a first signal integrating means for integrating a first signal for a first amount of time, wherein the first signal comprises a background signal;
- and
- a second signal integrating means for integrating a second signal for a second amount of time, wherein the second signal comprises a signal of interest and the background signal, wherein first and second capacitors have impedance values in a first ratio, and wherein the first amount of time and the second amount of time define a second ratio corresponding to the first ratio.
