Abstract
Provided are methods and systems for concurrent imaging at multiple wavelengths. In one aspect, an imaging device includes at least one objective lens configured to receive light backscattered by an object, a plurality of pixel array photo-sensors, a plurality of bandpass filters covering respective photo-sensors, where each bandpass filter is configured to allow a different respective spectral band to pass through the filter, and a beam steering assembly in optical communication with the at least one objective lens and the photo-sensors. The beam steering assembly directs light received by at least one objective lens from the tissue of a subject to at least one pixel array photo-sensor in the plurality of pixel array photo-sensors. The device further permits capture of near infrared images emitted by indicator molecules.
