IN VIVO IMAGING DEVICE, SYSTEM AND METHOD

摘要

An autonomous in vivo sensing device (40) may include a polarizing filter (706,712) to polarize light emitted by an illumination unit (23A), and to block light specularly reflected from a turbid media from reaching an imager (24A) of such device. An autonomous in vivo sensing device with monochromatic illumination units (30A,30B,30C) to altematingly illuminate a target area with light of different wavelengths, and to subtract an image illuminated by light in a first wavelength from an image illuminated by light in a second wavelength, to produce an image of a sub-surface layer of such target area.
