Abstract: An apparatus for reading images of a photographic film disposed on an image reading optical path, with a light source (31a) for emitting visible light and infrared light into the image reading optical path to irradiate the photographic film, and a zoom lens unit (32a) for the visible light and infrared light irradiating the photographic film. A visible light sensor and an infrared light sensor are disposed separately for detecting a visible image based on the visible light from the zoom lens unit, and for detecting an infrared image based on the infrared light from the zoom lens unit, respectively. A focal position varying transparent element (FT) is provided for shifting a focal position of the zoom lens unit along an optical axis. The transparent element is movable to and from a position between the zoom lens unit and infrared light sensor to correct variations in the focal position occurring with variations in magnification of the zoom lens unit.

Abstract: An infrared detector (10) includes a substrate (16) having thereon an array of detector elements (21, 139). Each detector element has a membrane (41, 81, 91, 111, 141), which includes an amorphous silicon layer (51, 142) in contact with at least two electrodes (53, 56-57, 92, 112-113, 143-145) that are made of a titanium/aluminum alloy which absorbs infrared radiation. In order to obtain a desired temperature coefficient of resistance (TCR), the amorphous silicon layer may optionally be doped. The effective resistance between the electrodes is set to a desired value by appropriate configuration of the electrodes and the amorphous silicon layer. The membrane includes two outer layers (61-62, 146-147) made of an insulating material. Openings (149) may optionally be provided through the membrane.

Abstract: A motion sensing system is disclosed having a housing or mounting, a sensor, a shield and a cover. A spacer and a printed circuit board may also be included. The cylindrical shaped sensor is placed within the cup shaped shield with the spacer disposed between the sensor and the printed circuit board. The shield and the printed circuit board are then fastened together. Next, the bottom or nose of the mounting shield is placed into the dish shaped cover and the combination is fastened to the housing with the cover extending into an opening in the bottom wall of the housing. The system allows a downward looking motion sensing capability in addition to the typical forward sensing capability which may also be installed in the housing. The housing may then be connected to a security lighting fixture. An even simpler version is a motion sensing system having a simple mounting for a two transducer PIR sensor where one of the transducers is covered and a Fresnel lens is absent. An effective short range motion detector results and the sensor may be aimed in any direction.

Abstract: A method for measuring trace quantities of OH groups in quartz glass comprises preparing a set of test pieces comprising a reference test piece from a blank of a quartz glass body whose OH group content is known and a sample test piece from a quartz glass body whose OH group content is to be measured, having two planar planes faced to each other, setting the sample test piece and the reference test piece in an infrared spectrophotometer; successively irradiating perpendicular to one of the two planar planes an incident infrared radiation in a wavelength region of approximately 2500 nm to approximately 2950 nm, while simultaneously detecting the outgoing radiation spectrum from the other plane; obtaining the difference of the outgoing radiation spectrum of each of the test pieces; selecting the absorbance peak assigned to OH groups at a wavelength of 2720 nm to obtain the peak height thereof; and calculating the concentration of OH groups from the peak height in the sample test piece.

Abstract: Provided are methods and apparatuses for the sensing of a property of a molten metal that lies beneath layers of interfering matter. A stream of gas is propelled into the layers of interfering matter at a velocity that is sufficient for the gas to penetrate through the layers of interfering matter and into the molten metal, thereby providing an opening through the layers of interfering matter. At the same time, energy emanating from the molten metal is detected and measured through the opening, so as to obtain an energy measurement. Then, the energy measurement is processed to determine a value for the desired property of the molten metal.

Abstract: A vernier ratchet-type lens adjuster for use with a lens array allows for fine adjustment of the coverage pattern of a sensor. The lens array can have notches, or teeth, that interact with a single tooth, or pawl, of a lens adjuster unit to maintain the position of the lens array. A user can make fine adjustments to the coverage pattern of the sensor by moving the lens array small increments. Alternatively, a rack and pinion type vernier adjuster can be used. One edge of the lens array has notches, forming the teeth of a rack portion. A pinion, or gear, has compatible teeth for mating with the rack portion. The pinion has a knob or screw accessible from a port in the sensor housing. When assembled, the rack, pinion and lens array are mated. A user can adjust the coverage pattern of the lens array by rotating the pinion, which in turn moves the rack, or the lens array, along a predetermined path.

Abstract: An advance in a passive, remote sensing device for measurement of atmospheric temperature utilizes an actuated modulator for periodically alternating the radiation detected by a detector at a selected infrared wavelength between the infrared radiation from the atmosphere and that from the infrared reference radiation emitted from a reference material such that the detector compares the radiation emitted from the atmosphere to that emitted by the reference material at the selected infrared wavelength in order to determine the atmosphere temperature. Preferably, the modulator is a MEMS based modulator having a movable grating formed by MEMS based fabrication techniques.

Abstract: A motion detector assembly for a decorative lighting fixture that conceals the presence of the motion detector in a decorative element integrated into the design of the lighting fixture and that uses only mirrored optics instead of Fresnel lenses. The motion detector assembly includes a housing having a decorative external appearance harmonious with the style of the lighting fixture and forming an integral part of the lighting fixture. Included within the housing are a mirror assembly and PIR sensor. The mirror assembly includes a number of mirror faces that define a number of monitored zones in the field of view. Each respective mirror face defines an optical path in which radiation admitted through an aperture in the housing from an associated zone is directed to the sensor solely by the respective mirror face without the need for secondary mirrors or auxiliary lenses to complete the optical path. The mirror assembly can provide for two or more vertical levels of view and can provide for a wide angular field of view at one or more of the vertical levels of view. The mirror faces are arranged in tiers, and at least one tier is formed with distal extremities extending forward and looking to the sides so that a ray path emanating from a zone at the lateral reaches the field of view passes beneath a first distal extremity and reflects off the mirror face at the other distal extremity to the sensor. With this disposition of mirror faces at the distal extremities the tier is able to define a field of view having an angular width of at least 160 degrees and, depending on the length and shape of the tier and angular configuration of the distal extremities, extending at least up to 220 degrees. An aperture cover transmissive to infra-red radiation conforms to the shape of the housing around the aperture but otherwise plays no optical role in the operation of the motion detector, thereby giving the lighting fixture designer more aesthetic freedom in designing the motion detector housing.

Abstract: A portable system for the real time detection and measurement of one or several gases is a gaseous mixture is disclosed. Such systems can be applied to industrial domains in which gases are to be measured and particularly toxic, dangerous, or polluting gases are generated. The system uses absorption spectrometry of a gas from a gaseous medium of interest. The optical means is at least two laser diodes with matchable cavities to generate a first and second wavelength, a light beam mixer prism, a double refraction crystal rotating on a controlled table. The tuned beam causes the gas to be measured to fluoresce and emit a signal to an infrared radiation detector which can indicate the identity and magnitude of the gas being measured.
