Abstract: Disclosed herein is a method comprising: sending radiation pulses (i), i=1, . . . , M one by one toward an object and toward an image sensor as the image sensor moves nonstop in a first direction with respect to the object; and for each value of i, capturing with the image sensor a partial image (i) of the object using radiation of the radiation pulse (i) that has transmitted through the object. The image sensor comprises N active areas. Each active area of the N active areas comprises multiple sensing elements. For each value of i, the radiation pulse (i) has a pulse duration during which the image sensor travels a distance shorter than a width measured in the first direction of any sensing element of the image sensor. M and N are integers greater than 1.

Abstract: The present disclosure describes a method for the formation of mirror micro-structures on radiation-sensing regions of image sensor devices. The method includes forming an opening within a front side surface of a substrate; forming a conformal implant layer on bottom and sidewall surfaces of the opening; growing a first epitaxial layer on the bottom and the sidewall surfaces of the opening; depositing a second epitaxial layer on the first epitaxial layer to fill the opening, where the second epitaxial layer forms a radiation-sensing region. The method further includes depositing a stack on exposed surfaces of the second epitaxial layer, where the stack includes alternating pairs of a high-refractive index material layer and a low-refractive index material layer.

Abstract: A method of detecting pulsed radiation comprising the steps of irradiating at least a portion of an array of sensor elements with pulsed radiation (71); addressing the array using a rolling shutter operation (72); reading the array to obtain a radiation image (73); and then applying a pulse detection operation (74) to the radiation image. The rolling shutter operation (72) is configured to address each element line of the array for a predetermined integration period. The predetermined integration period being calculated using an integration period function, itself a function of an anticipated pulse repetition interval of the pulsed radiation. The method and apparatus for the same enable low cost camera arrays to be used for pulse detection and for wider application in the field of low cost communications.

Abstract: A light sensor and its calibration method are provided. The light sensor includes a light source, a sensing sub-pixel, and a control circuit. The light source emits a sensing light beam. The sensing sub-pixel includes a diode, a quenching resistor, and a time-to-digital converter. The diode has a first terminal coupled to an operation voltage. The quenching resistor is coupled between a second terminal of the diode and a ground voltage. The time-to-digital converter is coupled to the second terminal of the diode. The control circuit is coupled to the sensing sub-pixel and calibrates a sensing sensitivity of the sensing sub-pixel according to at least one of a photon detection probability, an internal gain value, and a resistance value of the quenching resistor corresponding to the diode of the sensing sub-pixel, so that the sensing sub-pixel generates a single-photon avalanche diode sensing signal only when receiving the sensing light beam.
