Abstract
An optical imaging device which receives an optical collimated input beam, the device having a pair of axicon lenses through which a beam is directed to generate a collimated ring beam, wherein the ring beam is scattered from a substance to generate a return beam, and to bypass a reflector that redirects the return beam to prevent the return beam from interfering with the input beam; and a detector which detects an image projected by the return beam.
