Due to the resulting valence barriers a high temperature coefficient of resistance is achieved (3.3%/K). Very thin Si/SiGe single crystal multi-layers are grown epitaxially. The detector array is based on a new type of high performance thermistor material.

We address all the main cost drivers as sensor size and production yield along with vacuum packaging, optical components and large volume manufacturing technologies. To achieve our cost target below â‚¬100 for the sensor system we evaluate the required performance and can reduce the sensitivity to 150 mK and pixel resolution to 80 x 30. Looking 15 m in front of the vehicle it can in case of an unavoidable impact activate a brake assist system or other deployable protection system.

It is designed for use with an automatic vision algorithm system as a sensor to detect vulnerable road users in traffic.

Ruthenium oxide resistors as sensitive elements of composite bolometersīenassai, M. Improvements in the performances of such detectors lead to consider them as realistic candidates for the detection of Dark Matter Individual particle detections, using an 241 Am source, have been used to calibrate the system in this temperature interval. The properties of such RuO 2 films, in the temperature range have been studied. Results from a massive composite bolometer made of a sapphire crystal and ruthenium oxide films are presented. International Nuclear Information System (INIS) Low temperature composite bolometers using RuO2 films as a thermistor Instruments based on FSB technology should have several advantages over current multiband bolometric radiometers including smaller and more compact cryogenic optics reduced demands on cryostat size and weight, high coupling efficiency, minimum constraints on the geometry in the focal. This system uses a bolometer as a coupled element of a tuned quasi-optical interference filter in which the absorption, the transmission.-dimensional transmission-line model. We propose a concept for radiometry in the millimeter, the submillimeter, and the far-IR spectral regions, the frequency selective bolometer (FSB). These features made possible the development of efficient bolometer arrays. The near ideal doping uniformity that can be achieved with the NTD process, the device simplicity of NTD Ge thermistors and the high performance of cooled junction field effect transistor preamplifiers led to the widespread acceptance of these thermal sensors in ground-based, airborne and spaceborne radio telescopes. Recent advances in the development of neutron transmutation doped (NTD) semiconductor thermistors fabricated from natural and controlled isotopic composition germanium are reported. Neutron Transmutation Doped (NTD) germanium thermistors for sub-mm bolometer applications Significant changes were instituted in the manufacturing techniques along with more stringent process controls which eliminated the selenium pure film and successfully produced 22study bolometers. The selenium pure film was identified as a potentially serious failure mechanism. Spectrographic analysis of failed bolometers revealed selenium pure zones in the insulating selenium arsenic (Se-As) glass film which surrounds the active sintered Mn, Ni, Co oxide flake. The selenium immersed, thermistor bolometer, IR detector failed due to spurious and escalating electrical noise outburst as a function of time at elevated temperatures during routine ground based testing in a space simulated environment.
