Patent ID: 8379220

Claim:
An imaging and measuring apparatus for the surface and the internal interface of an object, comprising: a broadband wave source, transmitting a broadband incident wave; a wave-splitting structure, splitting said broadband incident wave into a first incident beam, a second incident beam, and a third incident beam, said first incident beam illuminating an object under test, and said object under test reflecting a measuring beam; a wave-delaying device, receiving said second incident beam, and reflecting a reference beam; a reflecting component, receiving said third incident beam, and reflecting a calibration beam; a rotationally scanning device, said rotationally scanning device disposed between said wave-splitting structure and said object under test for receiving and scanning said first incident beam and receiving said measuring beam; and a sensor, receiving a first interference signal of said measuring beam and said reference beam, said first interference signal being the imaging signal for the surface and the internal interface of an object, receiving a second interference signal of said reference beam and said calibration beam, and said second interference signal being used for compensating phase deviations.
