SYSTEMS AND METHODS FOR SPECTRAL IMAGING WITH A TRANSMITTER USING A PLURALITY OF LIGHT SOURCES
First Claim
1. An imaging device, comprising:
- A) a housing having an exterior and an interior;
B) an objective lens within the housing and flush with a surface of the housing so that the objective lens does not substantially extend past the surface of the housing;
C) a plurality of light source sets attached or integrated into the housing, wherein each respective light source set in the plurality of light sources sets comprises a plurality of lights that is uniformly radially distributed about the objective lens, whereina first light source set in the plurality of light source sets emits light that is substantially limited to a first spectral range, anda second light source set in the plurality of light source sets emits light that is substantially limited to a second spectral range other than the first spectral range;
D) a single two-dimensional pixelated detector within the housing and in optical communication with the objective lens;
E) a controller, wherein at least one program is non-transiently stored in the controller and executable by the controller, the at least one program causing the controller to perform the method of;
i) concurrently firing the plurality of lights in the first light source set for a first time period while not firing any other light source set in the plurality of light source sets,ii) collecting light from the objective lens during all or a portion of the first time period using the two-dimensional pixelated detector,iii) concurrently firing the plurality of lights in the second light source set for a second time period while not firing any other light source set in the plurality of light source sets, andiv) collecting light from the objective lens during all or a portion of the second time period using the two-dimensional pixelated detector, thereby forming at least one digital image.

Abstract
Systems and methods for imaging using a plurality of light sources is provided. An imaging device comprises a housing, a lens within the housing, a plurality of light source sets attached or integrated into the housing, a two-dimensional pixelated detector within the housing in optical communication with the lens, memory and a controller. Each respective light source set comprises a plurality of lights uniformly radially distributed about the lens. A first light source set in the plurality sets emits light substantially limited to a first spectral range. A second light source set in the plurality of sets emits light substantially limited to a second spectral range other than the first range. At least one program non-transiently stored in the memory and executable by the controller sequentially and independently fired each light source set while collecting light using the pixelated detector. An imaging device can be integrated with a mobile device.
