SCANNING MINIATURE OPTICAL PROBES WITH OPTICAL DISTORTION CORRECTION AND ROTATIONAL CONTROL

摘要

It include sheath the present invention relates to a kind of optic probe (130); One kind, can the optical delivery of bidirectional rotation be located in the sheath using system (10,135,137), (44); It is located at sheath with a kind of viscous damping fluid (140). The optical transmission system can transmit, and acquire projection-type image display and focus on predetermined wavelength range. Sheath and viscous damping fluid are that light of at least some of wavelength of transpath component. Index refracion viscosity usually is chosen so as to be caused to propagate through the sheath by optical effect. There is optic probe diameter to be approximately less than 500 ν m for scanning light from length, fiber (10) sample of high flexibility. In one embodiment, which includes that viscous damping fluid is suitable for preventing non-uniform rotational distortion (NURD). This probe can be used for optical coherence tomography (OCT) and other inerferometric imagings and range-measurement system, and transmission (such as fluorescence) or therapeutic light source for other imaging modalities.
