An air purge system for an optical sensor is disclosed. The air purge system includes a two sided lens having an optical sensor positioned on the first side and a fluid stream on the second side. The air purge system further includes, a plenum having an inlet, an array of parallel channels and an outlet, whereby the array of parallel channels, is disposed between the inlet and the outlet. The outlet is positioned on the second side of the housing and may be adapted to direct a fluid stream substantially parallel to the second side of the lens.

Air purge system for optical sensor

A contamination detection apparatus is provided for measuring an amount of contamination on an optically transmitting element or pane. The optically transmitting element is capable of transmitting electromagnetic radiation. The contamination detection apparatus includes a contamination detection (CD) radiation source for providing a source intensity of radiation. The source intensity or radiation passes through the optically transmitting element at least one time. A reference detector is also provided for detecting the source intensity of radiation, and the reference detector has a reference output level that is representative of the source intensity.

Window contamination detector

A light detector is disclosed for measuring the temperature of an object. The light detector includes a lens assembly for accepting light emitted from the object, an aperture, and a mirror for reflecting the infrared energy of the object into a fiber optic cable. The fiber optic cable is connected to a depolarizing element to which pressure is externally applied. The depolarization element relays the infrared energy into a detection portion and a signal processing portion for calculating temperature. Before the infrared light enters the fiber optic cable, a chopper, controlled by a driving circuit, chops the infrared energy reflected by the mirror.

Non-contacting infrared temperature thermometer detector apparatus

A scanning radiation sensor (10) for individually determining temperature of a plurality of spots (16') along a scan line (16) on a target (12) responds to inputs to a light marking apparatus (21, 29, 40, 21) to determine which of a plurality of samples produced during a scan cycle are to be selected for averaging (54, 54'). Averages are determined for each scan (54, 54') and then averages for each scan are averaged over multiple scans (56). Both spot target samples (Ts) and reference source samples (Rs) are averaged for improved accuracy, with target samples being converted to temperatures (52) before averaging.

Scanning radiation sensor for multiple spots and apparatus and method of

A scanning radiation sensor (10) automatically focuses a focusable optical system (26) based on the closest distance (C) and the farthest distance (F) of the optical system (26) from a target (12) through means of a focusing controller (44), motor driver (42) and focus motor (40) to obtain an optimum focus for all points along a line between the farthest point (f) and closest point (c).

Scanning radiation sensor with automatic focus control for optimal focus

A solid state laser visible light source (26) passes light through a scanning mechanism (22) otherwise used to convey radiation from a target (12) to a detector (28) of a scanning radiation sensor (10) to mark with light a line (16) which is continuous when the sensor (10) is operating in a continuous mode, but when the sensor is operated in a spot mode in which a plurality of spots along a scan line are to be individually measured, a control (30) causes the light source to turn on and off at the correct times in the scan cycle to cause the light source (26) to mark the plural spots on the scan line (16). A CCD camera (40) with an automatic gain control circuit (46) is used in conjunction with a band pass light filter (36) to substantially enhance viewability of the image of the light markings (16) on the target (12) on a display (44).
