Abstract:
Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.
Abstract:
A system for sensing and maintaining the light level within an area. The invention comprises multiple lux sensor readers that function to measure the current light level within an area. The readings are averaged such that over time any extreme readings are averaged out. The light level of the plurality of light sources (28) is adjusted in accordance with the averaged readings. The system includes control units (26), controllers, controls for window, skylight, light pipe and shading, HVAC controls, lighting loads (28) and light sensors (22), that are used to construct the lighting control system of the present invention.
Abstract:
The invention concerns input screens for radiological image intensifier tubes. The input screen comprises a scintillator (12) deposited on an aluminium substrate (10). It converts the incident X-rays into visible photons which then excite a photocathode (16). The luminous photons produced by the scintillator are emitted backwards and reflected by the aluminium layer, but this reflection reduces the resolution. According to the invention, to get rid of this reflection, it is proposed to make an input screen in which a thin film (20) which is transparent or only slightly absorbent at the wavelengths emitted by the scintillator between the substrate and the scintillator designed to provide an anti-reflective effect. The slightly absorbent anti-reflective film will preferably be selected from among indium, antimony, tin or bismuth oxide or a combination thereof, like indium-tin oxide. The thickness is a few hundred to a few thousand angstroms.
Abstract:
PROBLEM TO BE SOLVED: To provide an image reading device which can correct variations in quantity of light irradiated from a plurality of light emitting elements in order to read an image in a short time, and to provide a program. SOLUTION: A light detection section 44 detects the quantity of light irradiated, respectively, from a plurality of light emitting elements arranged along a predetermined direction and reflected by a standard board, a CPU 70 derives the deviation of the average value of the quantity of light each of a predetermined number of adjoining light emitting elements from a reference value based on the quantity of light detected at the light detection section 44, and then adjusts the quantity of light each of the predetermined number of adjoining light emitting elements so that the average value becomes the reference value based on the deviation thus derived.

Abstract:
An image pickup apparatus capable of reducing influence of flicker while suppressing delay of start of photographing. An image pickup device and a photometric sensor pick up images of an object. A CPU obtains images by controlling driving of one of the device and the sensor to perform charge accumulation and charge readout. Further, the CPU detects a flicker frequency and a flicker phase of a flicker light source, and stores them in a memory as first information. When photographing, if the CPU determines that the first information is not valid, an ICPU obtains images by controlling driving of the other of them to perform charge accumulation and charge readout. Further, the ICPU detects the flicker frequency and the flicker phase and stores them in a memory as second information. The CPU controls exposure timing according to the second information to perform photographing.
