Common path systems and methods for frequency domain and time domain optical coherence tomography using non-specular reference reflection and a delivering device for optical radiation with a partially optically transparent non-specular reference reflector

uspto.gov Oct 26 2010 Patents , Probes

Provided are common path frequency domain and time domain OCT systems and methods that use non-specular reference reflection for obtaining internal depth profiles and depth resolved images of samples. Further provided is a delivering device for optical radiation, preferably implemented as an optical fiber probe with a partially optically transparent non-specular reflector placed in the vicinity of an associated sample. High frequency fringes are substantially reduced and a stable power level of the reference reflection is provided over the lateral scanning range. The partially optically transparent non-specular reflector is implemented as a coating placed on the interior surface of the ...
