Abstract
Official abstract text for this publication.
A microbolometer detector with adjustable spectral reactivity includes a reflective element between a suspended pixel body and a base section, a bimetallic arm, one end of which is connected to one end of the reflective element and the other end to the base section via the electrode connection, the temperature of which is increased by passing current, and changes the height of the reflective element by expanding with the increase in temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. A microbolometer detector with an adjustable spectral reactivity, comprising: a reflective element, wherein the reflective element is located between a suspended pixel body and a base section, a bimetallic arm, wherein a first end of the bimetallic arm is connected to one end of the reflective element and a second end of the bimetallic arm is connected to the base section via an electrode connection, the bimetallic arm changes a height of the reflective element by expanding with an increase in temperature, the temperature of the bimetallic arm is increased by a passing current through the bimetallic arm. 2. The microbolometer detector according to claim 1 , further comprising a bimetallic arm containing metal/metal alloy structures with different expansion coefficients.
