OG exemplary drawing
 
1. An optical module comprising:
a housing comprising (1) a first portion configured to releasably couple to a scope and (2) a second portion configured to releasably couple to a camera;
an image sensor in the housing; and
an optics assembly disposed in the housing, wherein the optics assembly is configured to (i) receive light signals that are reflected from a target site within a subject's body and transmitted through the scope, and (ii) reflect a first portion of the light signals onto one of the image sensor or the camera, while permitting a second portion of the light signals to pass through to the other one of the image sensor or the camera so as to enable multi-wavelength imaging of the target site;
wherein the image sensor is configured to detect wavelengths with in a first range and the camera is configured to detect wavelengths within a second range different from the first range, and wherein the first range or the second range comprises reflected light signals comprising laser speckle from the target sight.
