      Gradient search integrated with local imaging in laser surgical systems

      Techniques and systems for gradient search are provided based on sensing or measuring at selected locations of a target object without performing full-field sensing or measuring over the entire field of the target object. Search methods are provided to include determining a coordinate of a boundary of a region in relation to a loop in a proximity of a first location, determining a direction of a gradient of the coordinate corresponding to the first location, and selecting a second location based on the determined direction. A search system can be implemented to include an imaging system to determine a coordinate ...

      Spectrometer With Adjustable Deflector For Controlling Alignment Of Dispersed Light On Detector, For Optical Coherence Tomography

      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 ...
