First Claim
Patent Images
1. A camera comprising:
- one or more spectral illuminators configured to emit active spectral light;
a tunable optical filter optically intermediate the one or more spectral illuminators and a scene, the tunable optical filter dynamically adjustable to change a selected sub-band of the active spectral light that illuminates the scene;
a sensor array including a plurality of sensors; and
a spectral controller machine configured to;
dynamically adjust the tunable optical filter to selectively transmit a selected sub-band of the active spectral light to illuminate the scene,for at least one spectral illuminator, activate the spectral illuminator if the spectral illuminator is configured to emit active spectral light in the selected sub-band, andaddress the sensors of the sensor array to measure spectral light reflected from the scene in the selected sub-band.

Abstract
A camera includes one or more spectral illuminators, a tunable optical filter optically intermediate the one or more spectral illuminators and a scene, and a sensor array. The one or more spectral illuminators are configured to emit active spectral light. The tunable optical filter is dynamically adjustable to change a selected sub-band of the active spectral light that illuminates the scene. The sensor array includes a plurality of sensors each configured to measure spectral light reflected from the scene in the selected sub-band.
