Abstract: A novel cassette structure technique for enabling simultaneous burn-in of pluralities of LEDs plugged into the cassettes, and then, with the cassettes mounted within a light integrating sphere system, separately measuring the spectral flux emitted by each successive individual LED plugged into the cassette to determine optical and electrical characteristics of each LED separately from the others.

Abstract: A method generally includes providing calibration node information to a user system communicably coupled to the calibration management system and associated with at least the user sensor, the calibration node information identifying a calibration node of a plurality of calibration nodes communicably coupled to the calibration management system and disposed at a plurality of geographical locations; receiving, from the user system, a request to access information generated via the calibration node; causing the calibration node to perform at least one calibration action based on the request, wherein the calibration action comprises at least one of: performing an environmental measurement to measure at least one aspect of an environment at the geographical location of the calibration node, or providing a calibration reference signal to the user sensor; receiving calibration results information containing results of the calibration action; and providing information associated with the calibration results information to the user system.

Abstract: A reflector array includes a support structure, a motor, a shaft operatively coupled to the motor, a free plate, and a drive plate. The free plate includes a free plate first side and a free plate second side axially opposed to the free plate first side. The free plate further may include a latching mechanism disposed on the free plate second side and a drive plate. The drive plate is rotatably coupled to the shaft. The drive plate includes a drive plate first side and a drive plate second side axially opposed to the drive plate first side. The drive plate further includes a drive plate finger coupled to the drive plate second side. The drive plate finger is configured to contact the latching mechanism in response to rotation of the driver plate. The drive plate finger is further configured to couple the drive plate to the free plate.

Abstract: A reflector array includes a base, a rotating support pivotally coupled to the base, and an array actuator comprising a rotating element coupled to the rotating support. The reflector array also includes a plurality of reflectors attached to the rotating support such that the plurality of reflectors rotate in unison in conjunction with one another relative to the base as the array actuator rotates the rotating element. First and second reflectors are coupled to the rotating support via separate reflector support elements that are rotatable to adjust elevation angles of the first and second reflectors.

Abstract: A system for calibrating a plurality of user sensors includes a calibration management system comprising a processor and a node services module and a plurality of calibration nodes disposed at a plurality of geographical locations. The processor is communicably coupled to the plurality of user sensors, the node services module, and the plurality of calibration nodes and operable to: provide calibration node information to a system associated with one of the plurality of user sensors and cause the calibration node to perform at least one calibration action after providing the calibration information, the calibration action may include performing an environmental measurement and/or providing a calibration reference signal to the user sensor. The processor is also operable to provide calibration results information containing results of the calibration action to the system associated with the one of the plurality of user sensors.

Abstract: A method of characterizing an imaging system includes generating a plurality of point spread function (“PSF”) samples using the imaging system, each PSF sample representing a response of an imaging system to a point illumination source, each PSF sample comprising one or more pixel values. The method also includes co-registering the pixel values contained in each of the plurality of PSF samples to form an oversampled point spread function (“PSF”) population; resampling the oversampled PSF population to uniform spacing to form a PSF image; slicing the PSF image in an evaluation direction to form a slice of the PSF image; and evaluating the slice to determine a value of a resolution metric of the imaging system that is specific to the evaluation direction.

Abstract: An illumination system includes an illumination source configured to emit illumination light and a dispersive optical element configured to generate an angularly dispersed optical signal from the illumination light that is used to generate a spectral image. A digital micro-mirror device (DMD) includes an array of reflective elements that receive the spectral image and direct a portion of the spectral image to an integrating sphere. A controller is configured to calculate a subset of an array of reflective elements of the DMD to activate based on a target illumination output signal using a calibration model of the illumination system. The controller is also configured to activate the subset of the array of reflective elements to change the portion of the spectral image directed to the integrating sphere to generate an illumination output signal that substantially matches the target illumination output signal.
