Abstract:
1. An imaging device comprising: imaging optics including a detector, the detector defining an xy plane including a first and a second detector region, the imaging optics configured to separate light by wavelength into a first and a second light, project the first light onto a first area on the first detector region, and project the second light onto a second area of the second detector region; a fiducial light source optically coupled to the imaging optics, the imaging optics configured to: a control system electrically coupled to the imaging optics, the control system configured to adjust alignment of the imaging optics so that the first fiducial light projected onto the first detector region maintains a relatively constant x-position and y-position on the first detector region and the second fiducial light projected onto the second detector region maintains a relatively constant x-position and y-position on the second detector region; and a processing unit configured to receive data from the first and second detector regions and adjust the data to account for photo-response non-uniformities on the first and second detector regions.
