Abstract:
A system and a method for irradiating an object and potentially for controlling the irradiation or other conditions relating to an effect of the irradiation. A sensor is translated along a longitudinal direction of the radiation emitter and in a space between the radiation emitter and the objects irradiated to arrive at information relating to a parameter relating to the effect of the irradiation, such as the radiation, and derived in the space between the radiation emitter and the objects irradiated. Calibrating the sensor readings and adjusting the radiating emitter output, thereby controlling the irradiation.
Abstract:
A safety control system comprises: a first control unit 12 arranged to control a controlled system 10, a second control unit 20 arranged to detect a fault with the controlled system and arranged to transmit messages wirelessly to the first control unit, wherein the second control unit 20 comprises: a first controller 24a and a second controller 24b, each of said first and second controllers being arranged to detect a condition of the controlled system 10 and output messages indicative of whether or not the condition has been detected; a transmitter 32 arranged to transmit wirelessly to the first control unit 12; and a multiplexer 30 arranged to connect each of the first and second controllers in turn to the transmitter so that messages from each of the first and second controllers can be transmitted to the first control unit.
Abstract:
There is provided a laser event recorder (100) comprising an image sensor, a processing unit coupled to the image sensor, and a wireless transceiver coupled to the processing unit. The processing unit is configured to identify when the image sensor is illuminated by a laser (16); in response to the identification, record a laser event comprising at least one characteristic feature of the laser (16); and send the recorded laser event to a central server (300) using the wireless transceiver. There is further provided an application software for configuring a smartphone as the laser event recorder, and a laser event recording system comprising the laser event recorder and the central server.
Abstract:
The present invention for imaging sensor rejuvenation may include a rejuvenation illumination system configured to selectably illuminate a portion of an imaging sensor of an imaging system with illumination suitable for at least partially rejuvenating the imaging sensor degraded by exposure to at least one of extreme ultraviolet light or deep ultraviolet light; and a controller communicatively coupled to the rejuvenation illumination system and configured to direct the rejuvenation illumination system to illuminate the imaging sensor for one or more illumination cycles during a non-imaging state of the imaging sensor.
Abstract:
Eine Vorrichtung zum Detektieren von Licht, insbesondere zur Anwendung in einem Mikroskop, einem Spektrometer oder einer Kamera umfasst mindestens einen Silicon Photomultiplier (SiPM), der aus einer Anordnung (Array) mehrerer Single Photon Avalanche Dioden (SPAD) besteht, wobei das Array eine größere Fläche als das auftreffende Licht aufweist und wobei nur diejenigen SPADs aktiviert und/oder ausgewertet werden, die mit einer bestimmten Mindestintensität von Licht beaufschlagt werden und/oder deren Funktion nicht unzureichend bzw. fehlerhaft ist. Ein Verfahren nutzt diese Vorrichtung.
Abstract:
The inventive sensor device includes a support structure, a sensing element mounted on the support substrate for sensing optical radiation and generating an electrical output signal in response thereto, and an encapsulant encapsulating the sensing element on the support structure. The encapsulant being configured to define a lens portion for focusing incident optical radiation onto an active surface of the sensing element, and an optical radiation collector portion surrounding the lens portion for collecting and redirecting optical radiation that is not incident the lens portion onto the active surface of the sensing element. The collector portion may be a parabolic reflector that reflects incident light by total internal reflection. The sensor device may be incorporated into an assembly including a diffuser positioned across an aperture, and/or may be incorporated into a vehicle accessory such as a rearview mirror assembly.
Abstract:
A light measurement method is provided comprising: determining one or more correction factors for at least one image capture device, using the image capture device to receive light output from at least one source of illumination, obtaining an output from the image capture device which corresponds to the light output of the source of illumination, and applying the or each correction factor to the output of the image capture device to obtain one or more substantially absolute measure of the light output of the source of illumination. A light measurement apparatus is also provided to carry out the light measurement method.
