摘要： A light integrator is mounted in a housing or cover that allows aligning the light integrator relative to a color wheel or other sequential color element. In some embodiments, a plate is attached to one end of a light rod and supports the light rod in the cover in a cantilever fashion or in combination with other support. The light rod is aligned to a light source, such as a lamp, and then the color wheel is aligned to the output of the light rod without altering the relationship between the light rod and the lamp.

摘要： This invention relates to attenuation filters having absorbing thin film layers, which comprises gray metals or metal compounds. The attenuation filters offer significant advantages when used in optical communication systems wherein they are subjected to a relatively high flux of incident light. It was surprisingly discovered that particular thin film materials provide significant protection to the attenuating thin films layer thereby improving the temporal stability and power handling capacity over prior art devices.

摘要： An infrared intrusion alarm system utilizes two sensing elements and two signal processing channels arranged such that an intruder produces signals of opposite polarities in the two channels. An alarm signal is delivered only in the event that the two signals of opposite polarities are present simultaneously. Disturbances, such as component noise, which affect only one channel cannot give rise to an alarm, nor can power supply disturbances which produce signals of the same polarity in both channels.

摘要： A rapid scan spectrum identifier fur use in identifying infrared spectrum of the output of a gas chromatograph to identify its absorption characteristics and includes an infrared source and beam splitter, a double beam chopper for alternately sending the infrared beam through a sample or reference gas cell mounted in a suitable furnace, the output of which is recombined and analyzed by a monochromator having a narrow output passband of energy detected by a rapid response detector, the output of which is processed by suitable electronic circuitry to provide a readout. The monochromator is of the scanning type in which a grating is synchronously scanned with a circular variable filter so that the first order output of the grating is selectively passed and higher orders rejected by the filter. The sample and reference gas cell furnace assembly utilizes specially constructed sample and reference gas cells symmetrically mounted in a furnace arrangement for maintaining input gas streams at equal temperatures within each cell and above the temperature of condensation of the sample under investigation. The beam chopper contains associated photoelectronics for physically determining the location of a chopping blade to thereby provide gating signals for indicating the presence at the detector of a sample, reference, or a background signals. These grating signals are used in sample and hold circuits to convert an essentially digitally sampled output into a relatively smooth continuous curve indicative of the absorption of the sample so that the readout represents the sample absorption characteristics corrected for reference for the carrier gas and background effects. The instrument is designed to operate with scan rates of approximately 6 and 30 seconds.

摘要： Infrared intrusion detector system utilizing a single sensing element and optical means for focusing radiation from one or more discrete fields of view onto the sensing element. An amplifier tuned to have a frequency response corresponding to the walking speed of an intruder amplifies the signal from the sensing element and provides means for discriminating between changes in infrared radiation due to the presence of an intruder and gradual temperature changes such as room or ambient changes.

摘要： An index-matching coating is applied directly to a low-emissivity (nulllowEnull) thin-film coating. Nodules growing from a site in the lowE coating are removed to avoid propagation of defects through the layers of the index-matching coating. A tempering step in an oxygen-containing atmosphere produces compressive stress in the lowE coating and hardens the coating. The compressive stress facilitates removal of the nodules and the hardening allows mechanical cleaning of the lowE coating prior to the index-matching coating, further removing nodules. Magnesium-fluoride is used as the final layer of the index-matching coating in one embodiment to improve abrasion resistance. The resulting glass panel may be used as a display panel in a plasma display or an organic light-emitting diode display, for example.

摘要： A multi-cavity optical device allowing selective control of a bandpass characteristic thereof . Fabry-Perot structures are coherently coupled together to form a narrow bandpass structure. At least one of the spacer regions in the device includes an active material that changes the optical thickness of the spacer to de-tune the device. In one embodiment, the active material is transparent and lies along the optical path through the device. In another embodiment, an active material that lies outside of the optical path tunes an air gap. Altering the first or last spacer in a multi-cavity structure provides variation in the transmission loss while generally retaining a flattop filter response with low passband ripple. Altering interior spacer regions provides high sensitivity to variations in the optical thickness of the spacer.
