Low-Cost Microbolometer Type Infrared Detectors

P5.11 Application and Design of Satellite Infrared Spectral Imaging Radiometers with Uncooled Microbolometer Array Detectors

Uncooled array detectors offer a number of advantages for space borne infrared array imaging. The elimination of detector cooling requirements can significantly reduce the size, cost and power requirements systems. Integration of the instrument to a spacecraft is much simplified due to reduced thermal management requirements. An array of detectors permits imaging without mechanical scanning. In...

A 64×64 pixel temporal contrast microbolometer infrared sensor

This paper presents a 64×64 pixel micro-bolometer based temporal contrast IR sensor. The pixels of the sensor independently and asynchronously respond to changes in thermal IR radiation and communicate respective events via arbitrated AER. A 46dB-gain, small-area, ultra low-power, low-mismatch differencing switched-capacitor amplifier has been designed for reading out the bolometer front-end. T...

Infrared detectors: an overview

The paper presents progress in infrared (IR) detector technologies during 200 history of their development. Classification of two types of IR detectors (photon detectors and thermal detectors) is done on the basis of their principle of operation. The overview of IR systems and detectors is presented. Also recent progress in different IR technologies is described. Discussion is focused mainly on...

History of infrared detectors

This paper overviews the history of infrared detector materials starting with Herschel’s experiment with thermometer on February 11th, 1800. Infrared detectors are in general used to detect, image, and measure patterns of the thermal heat radia− tion which all objects emit. At the beginning, their development was connected with thermal detectors, such as ther− mocouples and bolometers, which ar...
