Abstract:
1. A common path frequency domain optical coherence reflectometer comprising: a source of an optical radiation; a directional element; a delivering device adapted to form and deliver an optical radiation beam to a sample, the delivering device having a proximal part and a distal part, the distal part of the delivering device including a reference reflector; an optical unit, optically coupled with the proximal part of the delivering device through the directional element; an optical element for producing a combination optical radiation by combining an optical radiation returning from the sample with a reference optical radiation reflected from the reference reflector; and a frequency domain optoelectronic registering unit adapted to register the combination optical radiation and including a data processing and displaying unit; wherein the optical unit includes an optical element for splitting an incoming optical radiation into two portions, and at least two optical paths adapted for the respective portions of the optical radiation to propagate therethrough; and wherein the at least two optical paths have an optical path length difference.
