Abstract

Optical imaging of tissue with low-coherence interferometry offers the potential of non-invasive imaging and the possibility of spectral analysis of tissue characteristics. We suggest an interferometric technique that allows us to determine the optical properties of reflective boundaries and backscattering sites in a scattering medium. The sample is placed in ore arm of a Michelson interferometer. The interferogram fringes are formed only when the difference between the optical paths in two arms is less than the coherence length. The positions of peaks in the interferogram provide the information on locations of reflective boundaries and backscattering sites. Simultaneously, the spectral properties about the scattering sites are retrieved by filtering the interferogram with various band-pass filters. We propose a low-coherence confocal interferometer in combination with a microlens array for parallel scanning and processing. The system has the capability of rejecting scattered light from out-of- focus planes.As a low-coherence light source, we use the white light continuum, which is generated by focusing amplified femtosecond pulses into a water containing cell. The white light continuum has the broad spectrum and high brightness.
