SPECTROMETER WITH ADJUSTABLE DEFLECTOR FOR CONTROLLING ALIGNMENT OF DISPERSED LIGHT ON DETECTOR, FOR OPTICAL COHERENCE TOMOGRAPHY.

摘要

A spectrometer is presented that includes s spectrally dispersive optical element (120) to spectrally disperse a received light, a leveraged-optics adjustable deflector (142-1, 142-2, 142-3) to adjustably deflect the spectrally dispersed light, and a detector array (160) to receive the spectrally dispersed and adjustably deflected light. The received light can inlcude an interference beam combined from a returned image beam and a reference beam in a Spectral Domain Optical Coherence Tomograph. The detector array can include a linear sensor array. The leveraged-optics adjustable deflector can include an optical element with an adjustable transmissive property or an adjustable reflective property, wherein the adjustable deflector is adjustable by a mechanical adjustment being optically leveraged into a smaller optical adjustment.
