Patent ID: 8493568

Claim:
An optical imaging apparatus, comprising: an optical source module including Cr-doped fiber (CDF) and at least one optical pumping source and without a beam splitter, wherein said optical source comprises two outputs at the two ends of the CDF, said two outputs interfere with each other, wherein one of said outputs is used as a reference light, and another one of said outputs is used as a sample light; a sample probe module for leading said sample light from said optical source module to a sample via a first light path, wherein a portion of said sample light is reflected or scattered by said sample to form an information light, wherein said information light is leaded out by said sample probe module; an interference module including at least one photo detector, wherein said interference module leads said reference light from said optical source module to said at least one photo detector via a second light path, and leads said information light from said sample probe module to said at least one photo detector via a third light path; and a signal processing unit electrically coupled to said photo detector of said interference module for analyzing a spatial information of said sample.
