Abstract
An adaptive spectral imaging device operable to analyze a scene includes a detector having a detector output signal and an optical system disposed in an optical ray path between the scene and the detector to image the scene onto the detector. A controllable optical disperser is disposed along the optical ray path between the scene and the detector. The controllable optical disperser has a disperser input command signal. A controller has a controller output signal responsive to the detector output signal. The controller output signal is provided to the controllable optical disperser as the disperser input command signal.

An adaptive spectral imaging device operable to analyze a scene, comprising:
- a detector having a detector output signal;
- an optical system disposed in an optical ray path between the scene and the detector, the optical system imaging the scene onto the detector;
- a controllable optical disperser disposed along the optical ray path between the scene and the detector, wherein the optical dispersion of the optical disperser is controllable, the controllable optical disperse having a disperser input command signal;
- and
- a controller having a controller output signal responsive to the detector output signal, the controller output signal being provided to the controllable optical disperser as the disperser input command signal.
An adaptive spectral imaging device operable to analyze a scene, comprising:
- a detector having a focal plane array and a detector output signal;
- an optical system disposed in an optical ray path between the scene and the detector, the optical system imaging the scene onto the focal plane array of the detector;
- a controllable optical disperser disposed along the optical ray path between the scene and the detector, the controllable optical disperser comprising an optical phased array having a disperser input command signal;
- and
- a controller having a controller output signal responsive to the detector output signal, the controller output signal being provided to the controllable optical disperser as the disperser input command signal, wherein the controller comprises a calculational routine operable to distinguish a target feature against a background of the scene.
A method for adaptively analyzing a scene, comprising the steps of
- imaging a scene onto a detector having a detector output signal, a ray path from the scene to the detector passing through a controllable optical disperser, wherein the optical dispersion of the optical disperser is controllable;
- and
- controlling the controllable optical disperser responsive to the detector output signal.
