Abstract:
PROBLEM TO BE SOLVED: To provide a calibration system for an infrared sensor responsive to electromagnetic radiation from various types of radiation sources or for all broadband detectors.SOLUTION: A calibration system includes a plurality of radiation sources 304 mounted on a base member 302 in a fixed manner and a positioning mechanism 306 mounted on the base member. Each of the radiation sources is maintained at a different temperature and configured to emit electromagnetic radiation. The positioning mechanism includes a movable member having a single degree of freedom with respect to a plurality of optical members 310 disposed on the movable member 308. Each optical member corresponds to one of the radiation sources and each optical member is configured to be movable at least between a calibration position and a non-calibration position. The optical member is configured, in the case where the optical member is at the calibration position, to receive electromagnetic radiation from the corresponding radiation source and to reflect the electromagnetic radiation to a detector.
Abstract:
Described herein is a luminaire controller (6) which is mountable within a luminaire head by means of fastening areas (33) provided in a wall (34) forming part of an upper housing part (32) and/or a baseplate (15), the upper housing part and the baseplate forming a body for the luminaire controller. A flexible light guide (13) is provided for transmitting light from the exterior of the luminaire head to a light sensor located within the controller (6). A lens (14) may be provided at one end of the light guide (13) at the wall of the luminaire head with the other end of the light guide being adjacent the light sensor. A terminal strip (36) and an antenna jack (37) are provided to which respective electrical connections can be made and an antenna (12) can be connected by means of an antenna cable (38).
Abstract:
A calibration method comprising, for each of one or more light sensors: (a) under influence of one or more substantially non-zero illumination levels in the target environment, using the light sensor to measure the sensed light level corresponding to each of these one or more illumination levels; (b) receiving a template light level value corresponding to each of the one or more illumination levels, representing the light level at a target location in the target environment substantially removed in space from the location of the light sensor, each of the one or more template light level values being assumed for the environment rather than measured by a light meter; and (c) determining a relationship between the sensed light level and the light level experienced at the target location, based on an evaluation of the one or more sensed levels relative to the one or more template light level values.

Ein optischer Sensor umfasst einen Lichtsender, einen Lichtempfänger, eine Auswerteeinheit, wenigstens eine Spiegeleinheit, welche mehrere Mikrospiegelelemente mit wenigstens bereichsweise reflektierender Oberfläche und eine mit den Mikrospiegelelementen in elektrischer Verbindung stehende Elektroden-Anordnung umfasst, und eine Steuereinrichtung, die dazu ausgebildet ist, die Spiegeleinheit durch Ansteuern der Elektroden-Anordnung zwischen wenigstens zwei unterschiedlichen Funktionszuständen zu verstellen. Die Spiegeleinheit umfasst ein zumindest im Wesentlichen transparentes Substrat, an dem die Mikrospiegelelemente angeordnet sind. Die Steuereinrichtung ist dazu ausgebildet, die Spiegeleinheit zeitweilig in einen Transmissionszustand zu stellen, in welchem sich die Mikrospiegelelemente in einer geöffneten Stellung befinden und auf die Spiegeleinheit einfallende Lichtstrahlung an den Mikrospiegelelementen vorbei durch das transparente Substrat hindurchgelangt.
Abstract:
The present invention provides methods and systems for measuring optical power that require neither alterations to the optical fiber nor physical contact with the optical fiber, the system including an optical fiber configured to propagate an optical signal, wherein the optical fiber includes a core and at least a first cladding layer, wherein a portion of the optical signal scatters out of the optical fiber along a length of the optical fiber to form scattered fiber light; a detector system configured to receive the scattered fiber light along the length of the optical fiber and to output a detection signal based on the received scattered fiber light; and a processor configured to receive the detection signal and to determine a power value of the optical signal based on the received detection signal.
Abstract:
A dynamic signal to noise ratio tracking system enables detection and tracking of ride vehicles within the field of view of the tracking system. The tracking system may include an emitter configured to emit electromagnetic radiation within an area, a detector configured to detect electromagnetic radiation reflected back from within the area, and a control unit configured to evaluate signals from the detector and control the ride vehicles or other equipment as a result of this evaluation.
