Electro-Thermal Characterization of a Multi-Moded Bolometer

Active Technology Project

Project Introduction

The Electro-Thermal Characterization of a Multi-Moded Bolometer characterize the electrical and thermal performance of large multi-moded bolometers for a new generation of far-infrared instrumentation. Multi-moded systems provide distinct advantages compared to current single-moded designs. By collecting more photons on each detector, multi-moded designs improve sensitivity by an order of magnitude.  One multi-moded detector can thus replace 100 single-moded detectors, providing two orders of magnitude reduction in detector count while simplifying instrument design, integration, and testing.

 

The project work will test a far-IR detector with 30 times the absorbing area as the bolometers flown on the Planck mission. Multi-moded systems provide distinct advantages compared to current single-moded designs. By collecting more photons on each detector, multi-moded designs improve sensitivity by an order of magnitude. One multi-moded detector can thus replace 100 single-moded detectors, providing two orders of magnitude reduction in detector count while simplifying instrument design, integration, and testing.
