  • Quantum optical coherence tomography data collection apparatus and method for processing therefor
    Patent number: 6882431
    Abstract: The disclosed Quantum Optical Coherence Tomography apparatus and method includes a source of quantum entangled photons and a quantum interference device. The pair of entangled photons is divided into two beams, one of which illuminates a semi-reflective object and the second of which is reflected from a variable optical time-delay element (VTE). The VTE is scanned and the quantum interference in the QID is recorded to build up a reflectance profile of the object. A real scanning produces a full tomographic reflectance image. A method of processing the data to eliminate the effects of optical dispersion is disclosed.
    Type: Grant
    Filed: November 26, 2002
