Thermal detector with bolometric effect amplification

摘要

This detector has a resistive element (4) able to undergo heating which is provided with electrical biasing means (6, 8) for amplifying or increasing the heating, a thermometer (12) thermally coupled to the element and converting a temperature variation undergone by the thermometer into an electric signal, and a device (18) for reading the electric signal. The invented detector can be applied to measure and detect infrared radiation. The detector can also be applied to measure and detect radiation of different wavelengths.
