Patent ID: 7821643

Claim:
A common path frequency domain optical coherence reflectometry device comprising: means adapted for generating an optical radiation; delivering means comprising: a proximal part, and a distal part including a focusing system and a partially optically transparent non-specular reference reflector, which is optically coupled with the focusing system, wherein the delivering means is adapted for forming and delivering an optical radiation beam to the partially optically transparent non-specular reference reflector, and delivering a first portion of the optical radiation beam to an associated sample via the partially optically transparent non-specular reference reflector placed in a vicinity of an associated sample, along a common optical path; directional means optically coupled with the means adapted for generating optical radiation and adapted for directing the optical radiation from the means adapted for generating optical radiation to the proximal part of the delivering means; and frequency domain optoelectronic registering means optically coupled with the directional means and comprising data processing and displaying means; wherein the partially optically transparent non-specular reference reflector is adapted for splitting the optical radiation beam into two portions prior to delivery of the first portion of the optical radiation beam to an associated sample, wherein the second portion is reflected by the partially optically transparent non-specular reference reflector; wherein the partially optically transparent non-specular reference reflector is further adapted for creating a combination optical radiation by combining an optical radiation returning from an associated sample with a non-specular reference optical radiation reflected from the partially optically transparent non-specular reference reflector; wherein the delivering means is further adapted for delivering the combination optical radiation to the directional means; and wherein the directional means is further adapted for directing the combination optical radiation to the frequency domain optoelectronic registering means.
