Abstract
The present disclosure provides systems, devices, and methods for imaging and imaging subject. The systems and devices may include one or more light filtering devices. The light filtering devices may include a chamber having an input and an output. The chamber may be configured to receive a beam of light. The chamber may comprise a plurality of reflectors configured to direct the light received in an optical path from the input to the output via reflectance of the light between one or more reflectors of the plurality of reflectors. The chamber may be configured to reject out of focus light along the optical path.

-20. (canceled)
A device, comprising:
- a probe configured to (i) direct a beam of light from a light source to an imaging subject and (ii) collect light from said imaging subject upon said beam of light contacting said imaging subject;
- and
- a light filtering device in optical communication with said probe, wherein said light filtering device comprises (a) a chamber having (i) an input configured to receive said light collected by said probe and (ii) an output configured to transmit a focused portion of said light away from said chamber and (b) a plurality of reflectors disposed in said chamber, wherein said plurality of reflectors is configured to direct said light received, in an optical path from said input to said output via reflectance of said light between reflectors of said plurality of reflectors, wherein said chamber is configured to reject out of focus light along said optical path.
A method for imaging an imaging subject, comprising:
- (a) providing a probe in optical communication with (i) a light filtering device comprising a chamber and (ii) said imaging subject;
- (b) transmitting said beam of light from a light source to an imaging subject via said probe and collecting light from said imaging subject upon said beam of light contacting said imaging subject.
- (c) using said probe to provide a beam of light to said imaging subject and collect a resulting return beam of light from said imaging subject;
- (d) directing said return beam of light from said imaging subject to said chamber of said light filtering device;
- (e) repeatedly directing said beam of light from a first reflector to a second reflector within said chamber of said light filtering device such that a pathlength that said beam of light traverses between said first reflector and said second reflector is at least three times a distance separating said first reflector and said second reflector;
- and
- (f) processing said beam of light to generate an image of said imaging subject.
