Endoscopic diffuse optical tomography (DOT) is a novel approach that can be used in imaging the optical absorption and scattering contrast in the internal organs. In endoscopic DOT, the sources illuminate outward from the internal surface of the organs and the detectors collect the diffused light from the same surface. This new kind of imaging geometry(More)
A compact static birefringent imaging spectrometer (BIS) with spectral zooming capability is presented. It based on two identical Wollaston prisms and has no slit. The most significant advantage of the BIS is that we can conveniently select spectral resolution to adapt to different application requirements and greatly reduce the size of the spectral image(More)
