Abstract: A method is provided for setting up a photon counting detector, to enable it to carry out a centroiding procedure in which a photon event occurring in a given range is allocated to one of a plurality of channels into which the range is divided. The method comprises the steps of: a) sub-dividing the range into a plurality of channels of preferably equal width and loading the channel boundaries into a look-up table; b) performing an integration on a flat field and allocating photon events to the channels defined in step a); c) counting the number of events allocated to each channel; d) altering the channel boundaries in directions tending to equalise the number of events allocated to each; and, optionally, e) repeating steps b), c) and d) until the variation between the numbers of events held by the channels is at an acceptable level.

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: 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.
