ABSTRACT:
A spectrometer is presented that can include a spectrally dispersive optical element to spectrally disperse a received light, a leveraged-optics adjustable deflector to adjustably deflect the spectrally dispersed light, and a detector array to receive the spectrally dispersed and adjustably deflected light. The received light can include 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.
