Most of the theories and methods reported in the literature [20-25] for estimating the figures of merit of a bolometer
are consistent with each other for any thermal detector and depend upon the characteristics of each design.
Samuel Langley's bolometer
in the late 1800s could detect the heat from a cow from as far away as one-quarter mile.
The latest is a "scintillating bolometer
", a 46-gram device that, in this case, contains a crystal "scintillator", made up of bismuth, germinate and oxygen, which acts as a dark matter detector.
Despite certain limitations, astronomers in the early 1960s quickly adapted the new germanium bolometers
to infrared telescopes in ground observatories.
The feasibility of a superconducting bolometer
operating at or above liquid nitrogen temperature has been indicated recently.
Contract award notice: Helium-cooled bolometer
(czechia-prague: Laboratory, Optical and precision equipments (excl.
On the basis of product type, the bolometer
segment is expected to remain highly attractive during the assessment period.
Ulis, a manufacturer of thermal image sensors, has announced a response time for its latest bolometer
that is four times faster than standard bolometers
The operation principle of these devices is based on change of the bolometer
resistance with an increase in the temperature.
The red dotted area in Figure 3 is zoomed and shown in Figure 4 for a more detailed view of excitation slot, CPW feeding lines, and bolometer
Glass and glass ceramics are very important materials for their device making applications such as cryogenic temperature sensors which include a capacitance thermometer, a dielectric bolometer
, and capacitive energy storage capacitors.
