Superconducting bolometer array with SQUID readout for submillimetre wavelength detection

, 2003
We have tested a fully microfabricated superconducting bolometer array for astrophysical observations at submillimetre wavelengths. The system is cooled by a He-3 sorption refrigerator operating in a pumped 4 He cryostat.

Radiation-harvesting resonant superconducting sub-THz metamaterial bolometer

, 2013
We demonstrate a frequency-selective energy-harvesting sub-THz superconducting bolometer. The bolometer, a two-dimensional array of connected metamaterial resonators, exploits the collective mode of the metamaterial excitation to collect incident ...

Ideal Integrating Bolometer

, 2004
We describe a new "ideal integrator" bolometer as a prototype for a new generation of sensitive, flexible far-IR detectors suitable for use in large arrays. The combination of a non-dissipative sensor coupled with a fast heat switch provides breakthrough

Optical Characterization of a Highly Multimoded Bolometer

, 2014
Highly sensitive bolometers have become standard tools for probing the cosmic microwave background (CMB). Recent efforts by ground and balloon based detectors have focused on making measurements of the polarization of the CMB in order to test ...

Undoped Lec GaAs as an Infrared Bolometer Detector

, 1994
Undoped LEC GaAs grown with very low residual acceptor concentration is often low resistivity with an activation energy for conduction of 0.43 eV. We demonstrate that this material can form a very sensitive bolometer element and show how large two ...

Vibrating ribbon bolometer: A concept

, 1972
Incident electromagnetic radiation pulses maintain bolometer's sensitive element in state of resonant oscillation and correlate amplitude of oscillation with incident radiation power.

The Arcminute Cosmology Bolometer Array Receiver (ACBAR).

, 2002
We describe the Arcminute Cosmology Bolometer Array Receiver (ACBAR) which is a 16 pixel, 240mK multifrequency bolometer array for measuring primary and secondary anisotropies in the CMB at millimeter wavelengths.

Bolometer Simulation Using SPICE

, 2004
A general model is presented that assimilates the thermal and electrical properties of the bolometer - this block model demonstrates the Electro-Thermal Feedback (ETF) effect on the bolometers performance.
