Patent ID: 7317540

Claim:
A method of generating an object image by optical coherence tomography with natural color representation, the method comprising the steps of: performing optical coherence tomography imaging on the object illuminated with a red LED resulting in a first image; performing optical coherence tomography imaging on the object illuminated with a blue LED resulting in a second image; performing optical coherence tomography imaging on the object illuminated with a green LED resulting in a third image; combining the first, second and third images to generate a fourth image having full natural color representation; wherein the step of performing optical coherence tomography imaging on the object illuminated with a red LED further comprises the steps of: illuminating the object with a reference wave; performing phase-shift interference imaging resulting in four image frames acquired at quarter wavelength intervals of the reference wave; extracting the first image from the resulting four image frames; and wherein the object of interest is biological tissue.
