Abstract: An optical sensor includes pixels. Each pixel has a photodetector. A readout circuit performs a process over an exposure time where the photodetector is connected to a reverse bias voltage supply to reset a voltage across the photodetector, and the photodetector is disconnected from the reverse bias voltage supply until that the voltage across the photodetector decreases in response to received ambient light. An ambient light level is then determine an based on a number of times the voltage across the photodetector is reset over the exposure time.

Abstract: An apparatus for characterization of one or more light sources over a field of view has an image relay disposed to relay a first image plane to a second image plane. An aperture defines the field of view at the first image plane. A diffraction grating in the path of light through the aperture is configured to form, on the first image plane, for at least one light source, a light pattern having at least two diffraction orders of light from the corresponding light source. An image sensor array is configured to provide image data from the light pattern at the second image plane.

Abstract: A method for operating a light microscope comprises emitting and guiding a plurality of illumination light beams towards a specimen (6) to form a plurality of separated illumination light spots (2A, 2B, 2C, 2D) at the specimen; and guiding detection light beams (11) coming from the illumination light spots (2A, 2B, 2C, 2D) to a detector (10) comprising a plurality of sensor arrays (31-34). Each sensor array (31-34) comprises photon-counting detector elements (40), and detection light beams (11) from different illumination light spots (2A, 2B, 2C, 2D) are guided to different sensor arrays (31-34). Measured signals from the sensor arrays (31-34) are analysed to determine positional information about the light spots (15) on the sensor arrays (31 -34). It is adjusted where the light spots (15) hit the sensor arrays (31-34) based on the positional information. A corresponding light microscope is furthermore disclosed.

Abstract: A light-receiving apparatus (1a) includes a counting unit (11), a setting unit (12), and an acquiring unit (13). The counting unit is configured to measure a detection number of times that represents the number of times incidence of a photon to a light-receiving element has been detected within an exposure period and to output a counted value. The setting unit is configured to set a cycle of updating time information in accordance with an elapsed time during the exposure period. The acquiring unit is configured to acquire the time information indicating a time at which the counted value reaches a threshold before the exposure period elapses.
