A thermal imager system for use in a vehicle utilizes an uncooled microbolometer detector array ( ), optics ( ) for conducting scene radiation to the array within a sensor module ( ) which is separate from an image processing and display unit ( ), to provide a small, direct view sensor module ( ) that may be oriented for forward viewing. The sensor module ( ) is mounted external to the vehicle and the image processing and display unit ( ) is mounted internal to the vehicle, and the two are connected by a noise immune bidirectional digital communication path or harness ( ). The optics ( ) consist exclusively of refractive optical components ( ) providing a straight line radiation path from the scene to the array ( ).

Uncooled driver viewer enhancement system

A microscanner (30, 32, 34, 36) is cascaded with the electromechanical scanners (12, 14) in imaging systems to enhance their performance and correct inherent deficiencies in the scanning and/or the displayed imagery.

Dynamic optical scanning correction device

A fluid flow meter using a pair of temperature-variable resistance elements as detectors. Both elements are exposed to the fluid flow and supplied with a series of current pulses. The pulses supplied to one element, the reference element, are of very short duration so as to have no appreciable heating effect; the pulses supplied to the other element are of longer duration and are controlled so as to maintain this element at a fixed temperature differential above the other element, which remains at fluid temperature. The pulse width of the longer duration pulses is a measure of the flow rate of the fluid. Since the relationship between heat dissipated in the element and fluid flow varies with fluid temperature, the voltage pulses across the reference element are used as a measure of fluid temperature to compensate for this variation in calculating the exact fluid flow rate.
