摘要： An OCT system is arranged to capture a three-dimensional (3D) OCT scan of a target. The OCT system projects a beam scan towards the target, and the OCT system generates data corresponding to the beam scan. Additionally, an image sensor is arranged to capture an image of a trace of the beam scan on a surface of the target. Using the image of the trace, various characteristics of the target are determined.

摘要： External cavity lasers with single mode-hop-free tuning are generally described. In an example, an external cavity tunable laser system includes an external cavity, a substrate, a chirped grating reflector, and a tunable filter. The substrate has a gain region disposed on the substrate and also includes an active waveguide. The external cavity tunable laser system has a cavity length of the external cavity tunable laser system that is defined by at least a first length of the chirped grating reflector, a second length of the gain region, and a third length of the tunable filter. The cavity length also has an inherent external cavity longitudinal mode. Further, the tunable filter and the chirped grating reflector are configured to synchronize to the inherent external cavity longitudinal mode over a tuning range of the tunable filter.

摘要： An optical coherence tomography (OCT) system combining multiple wavelengths is generally described. In an example, the OCT system includes multiple wavelength swept light sources. The system further includes an interferometer into which light from the light sources is directed and a detector configured to produce an imaging sample signal based on light received from the interferometer. The system also includes a splitter configured to split light from at least one of light sources before the light reaches the interferometer. The system also includes a wavelength reference filter having an equal interval frequency comb and a signal processing circuit. The wavelength reference filter is configured to produce a sequential clock waveform from light received from the splitter, and the signal processing circuit is configured to resample the imaging sample signal based on the sequential clock waveform.

摘要： Optical coherence tomography (OCT) systems using a polarization switch and/or a polarization beam splitter are generally described. In an example, an OCT system includes a light source configured to emit a beam and an interferometer configured to receive the beam. The interferometer includes a reference path and an interferometer sample path. The OCT system further includes a polarization switch configured to selectively change a polarization state of the beam and a lens system that includes a first sample path and a second sample path. The polarization switch is further configured to direct the beam onto the first sample path upon selection of a first polarization state and to direct the beam onto the second sample path upon selection of a second polarization state that is different from the first polarization state.
