Abstract: Operational parameters of a single-photon detector are determined with a continuous wave laser source. At a fixed trigger, a dark count probability and a series of count probabilities at different optical powers are determined. A particular optical power is selected by using a wide-range variable attenuator to attenuate the optical power of the continuous wave laser. The dark count probability and the count probabilities are determined for different trigger rates. The operational parameters include efficiency, afterpulsing constant, and detrap time. The operational parameters are computed by fitting the computed dark count probabilities and count probabilities to a user-defined relationship.

Abstract: A system with a machine and a lighting device. The machine includes an image capture device and a machine vision processing system configured to detect a characteristic of a subject in a space for an operation of the machine. The lighting device includes a first light source for generating light to illuminate the space, and a second light source for generating light of a particular wavelength to support detection of the characteristic of the subject via the machine vision processing system. The light of the particular wavelength is output at a sufficient intensity reasonably expected to produce a particular emission from the subject detectable via the image capture device different from an emission produced by exposure of the subject to the light for illumination of the space. The first and second light sources are integrated into the lighting device.

Abstract: The present disclosure describes systems, methods, and devices for estimating spectral contributions in ambient light. The present disclosure also describes systems, methods, and devices for compensating for field of view errors resulting from the user, contextual structures (e.g., buildings, trees, fixtures, or geological formations), atmospheric effects (e.g., ozone coverage, smog, fog, haze, or clouds), device structures, and/or device orientation/tilt relative to a light source being measured (e.g., sun, indoor/outdoor light emitter, or an at least partially reflective surface). The present disclosure also describes systems, methods, and devices for estimating spectral contributions in light or color measurements and accounting for field of view errors to obtain a refined estimate.

Abstract: A stroboscope with an integral optical reflective sensor, which can be removable or fixed, contains a light emitting source, a light sensitive receiver, a pulse conditioning circuit, a stroboscope circuit, a blanking circuit, and a stroboscope light source. The light emitting source projects a light beam to a reflective target. The reflected light beam from the reflective target is detected by the light sensitive receiver. The pulse conditioning circuit generates a set of electrical pulses coincident with the reflected light beam which are sent to the stroboscope circuit. Depending on the signal received by the stroboscope circuit, the stroboscope light source is triggered. The blanking circuit prevents false triggering of the stroboscope light source by introducing a time delay. The time delay is applied when the stroboscope light source is switched on and for a finite time after the stroboscope light source is switch off.

Abstract: A light emitting module testing apparatus includes a sensing unit and a controller. The sensing unit includes a photodiode array sensing light emitted from a light emitting module serving as a test object. The controller generates luminance information based on light sensed by the sensing unit, and sets an operating condition of the light emitting module serving as the test object by comparing the generated luminance information with a pre-set reference range. The light emitting module testing apparatus thereby senses luminance of light emitted from the light emitting module serving as a test object, and sets the operating condition of the light emitting module to have an appropriate luminance.
