Abstract: A temperature dependent focal plane array operates without a temperature stabilization cooler and/or heater over a wide range of ambient temperatures. Gain, offset and/or bias correction tables are provided in a flash memory in memory pages indexed by the measured temperature of the focal plane array. The memory stores a calibration database, which is accessed using a logic circuit which generates a memory page address from a digitized temperature measurement of the focal plane array. The calibration database is comprised of an array of bias, gain and offset values for each pixel in the focal plane array for each potential operating temperature over the entire range of potential operating temperatures. The bias, gain and offset data within the database are read out, converted to analog form, and used by analog circuits to correct the focal plane array response.

Abstract: A passive, real-time obstacle detection system is provided that determines the presence of small, curvilinear objects such as power lines. The system generally comprises a payload system having an infrared image detection system, a crew interface having a display for the images, and software algorithms that perform image processing on the pixel images. The software algorithms employ Cellular Automata (CA) techniques to resolve the direction vectors of sub-pixels, and as such, line segments are produced that are subsequently linked for display to the flight crew. The CA techniques are further based on the nullGame of Lifenull model, wherein local rules are used to determine how pixels evolve, or propagate along a line. The linked lines are then displayed for the flight crew so that evasive maneuvers can be performed as necessary.

Abstract: A radiant light from a reaction chamber is measured outside the chamber, and a relation between a change of a radiation ratio of the radiant light, and a change of a thickness of a thin film is acquired, when a CVD apparatus is used to form the film on a substrate in the chamber. After acquiring the relation between the change of the radiation ratio and the change of the film thickness, the change of the radiation ratio is measured, when the CVD apparatus is used to form the film. The thickness of the film is estimated from the change of the radiation ratio measured in measuring the change of the radiation ratio from the relation between the change of the radiation ratio and the change of the film thickness acquired in acquiring the relation between the change of the radiation ratio and the change of the film thickness.

Abstract: An infrared ray detector includes an array of pixels each including an infrared ray sensitive section having a first thermo-sensitive resistor and an infrared ray non-sensitive section having a second thermo-sensitive resistor. The second thermo-sensitive resistor is covered by an infrared ray reflector film. A pair of visors extending from the first thermo-sensitive resistor overhang the adjacent second thermo-sensitive resistor. A difference between the output signals from the first and second thermo-sensitive resistors is delivered as an output signal which cancels the fluctuation caused by the ambient temperature or Joule heat of the bias current.
