Abstract:
1. An imaging device suitable for simultaneously imaging a plurality of light wavebands, comprising: an objective lens assembly comprising a first prism and a second prism disposed along a central axis of the objective lens assembly, wherein the objective lens assembly is operatively configured to receive light reflected from an object through an entrance pupil, the first prism is operable to internally reflect a first light waveband to a transmitting surface of the first prism and pass a second light waveband to the second prism, and wherein the second prism is operable to internally reflect the second light waveband to a transmitting surface of the second prism; a first camera disposed along an optical path after the transmitting surface of the first prism, wherein the first camera comprises a first waveband objective lens assembly, which includes a first plurality of lenses, configured to receive the first light waveband and a first detector, the first waveband objective lens assembly configured to refract the first portion of the light exiting the first prism to form a first image at the first detector; and a second camera disposed along an optical path after the transmitting surface of the second prism, wherein the second camera comprises a second waveband objective lens assembly, which includes a second plurality of lenses, configured to receive the second light waveband and a second detector, the second waveband objective lens assembly configured to refract the second portion of the light exiting the second prism to form a second image at the second detector; and a processor configured to synchronize control of the first camera and the second camera such that the first detector and second detector simultaneously capture a respective image of the object as viewed through the entrance pupil of the objective lens assembly.
