4.1 Bolometers
4.1.1 Principle of bolometric detection
In a bolometer, the incident THz beam is absorbed and heats a material. The electrical resistivity of this material, or of a material adjacent to the absorbing material, depends on temperature. The absorbed THz power P THz , which increases the temperature T of the material, is determined by measuring the change in resistance R of the material, i.e. by simply applying a voltage V to the material and reading the value...
