Nonlinear Modeling of RF Thermistor: Application to Bolometer Mount Calibration
IEEE Transactions on Instrumentation and Measurement, 2011 International audienceThe radio frequency (RF) bolometer thermistor has been studied over a wide frequency range. A novel equivalent electrical model is presented to show the nonlinear behavior of the bolometer thermistor for different polarization ...

The theory of a thin bolometer strip is developed. It explains observation of enhanced response to spot illumination near the trip terminals, and predicts enhanced thermal fluctuation at the same point for uniform chopped illumination.

Subsurface damage detection of a steel bridge using deep learning and uncooled micro-bolometer
Construction and Building Materials, 2019A new deep learning-based method is proposed to detect subsurface damage of steel members in a steel truss bridge using infrared thermography (IRT). To reduce computation costs, the original deep inception neural network (DINN) is modified for transfer ...

2D Material-enabled Nanomechanical Bolometer.
Nano letters (Print), 2020We here describe a novel type of long-wavelength radiation detector that measures illumination intensity at room temperature through mechanical transduction. Compared to semiconductor-based bolometers, our nanomechanical detector exhibits low measurement

Graphene Aerogel Based Bolometer for Ultrasensitive Sensing from Ultraviolet to Far-Infrared.
ACS Nano, 2019This work uncovers that free-standing partly reduced graphene aerogel (PRGA) films in vacuum exhibit extraordinarily bolometric responses. This high performance is mainly attributed to four structure characteristics: extremely low thermal conductivity (6.

ULIS bolometer improvements for fast imaging applications
Defense + Commercial Sensing, 2019Thermal Image Sensor performances for high end applications can be compared using a Factor of Merit (FoM) based on NETD and thermal time constant (τth). This FoM is defined as FoM = NETD × τth and is expressed in mK.ms. Best bolometers FoM range from 500

A Fast Superconducting Bolometer*
Journal of the Optical Society of America, 1946A superconducting bolometer has been developed for the fast detection of infra-red signals. It has a compound response in which the primary response time is about 5 × 10−4 sec. and the secondary response time about 5 × 10−2 sec. In the primary range a signal of 5 × 10−4μ watt is equivalent to the noise of the apparatus.

Frequency selective bolometers
Applied Optics, 1996We propose a concept for radiometry in the millimeter, the submillimeter, and the far-IR spectral regions, the frequency selective bolometer (FSB). This system uses a bolometer as a coupled element of a tuned quasi-optical interference filter in which the absorption, the transmission, and the reflection characteristics of the filter depend on the ...
