Abstract:
1. A thermistor bolometer comprising: a front connector block comprising bellows springs utilized for DC and low frequency ground connection; a bottom housing; and a substrate, wherein the substrate rests in the bottom housing and is pressed into a slot in the front connector block; the substrate comprising at least two coplanar waveguides arranged symmetrically on both sides of the substrate, and a center conductor that makes electrical contact with a middle conductor of the at least two coplanar waveguides; and wherein a termination resistance of each of the at least two coplanar waveguides is provided by at least two thermistors, with one thermistor per coplanar waveguide; and wherein the at least two thermistors are held at a desired resistance by application of DC current from an external source, forming a sensor of a DC substitution bolometer.
