CONTEXT

A bolometer usually includes a variable resistance depending on the temperature and a body absorbing the incident radiation or another external signal. The extent of the change in this resistance allows a measure of this temperature, allowing itself back to the variation of the incident external signal. The operation principle of bolometer is based on relatively slow thermal phenomena, even if it's envisaged the miniaturization that allows reducing the time constants. The Performance improvement of the bolometers is a key point to increase the sensitivity and the response time of the targeted applications.
