    Abstract: Calibrating a spectrometer module includes performing measurements using the spectrometer module to generate wavelength-versus-operating parameter calibration data for the spectrometer module, performing measurements using the spectrometer module to generate optical crosstalk and dark noise calibration data for the spectrometer module, and performing measurements using the spectrometer module to generate full system response calibration data, against a known reflectivity standard, for the spectrometer module. The method further includes storing in memory, coupled to the spectrometer module, a calibration record that incorporates the wavelength-versus-operating parameter calibration data, the optical crosstalk and dark noise calibration data, and the full system response calibration data, and applying the calibration record to measurements by the spectrometer module.

    Abstract: An eye-safe optoelectronic module includes a light source mounted on a support and operable to generate light along an emission axis. An eye-safe substrate has an eye-safe substrate refractive index and includes at least one diffusive surface. The eye-safe substrate is mounted such that the emission axis is intercepted by the diffusive surface. An optical assembly includes at least one optical element, is composed of an optical material and is mounted on the diffusive surface of the eye-safe substrate such that the optical material fills a diffusive surface of the eye-safe substrate. The optical assembly has an optical assembly refractive index that is substantially the same as the eye-safe substrate refractive index.

    Abstract: The disclosure describes optoelectronic devices for collecting three-dimensional data without determining disparity. The approach permits significant flexibility relative to state-of-the-art approaches for collecting three-dimensional data. For example, the illuminations (e.g., patterns) generated by the disclosed devices need not exhibit the same degree of complexity or randomness of illuminations generally required by structured-light approaches. Further, the devices described in the present disclosure exhibit, in some instances, optimal resolution over a wide distance range. An optoelectronic device described herein is operable to generate an illumination comprising a plurality of high-intensity features that exhibit a distance-dependent alteration when imaged by an imager incorporated into the optoelectronic device.
