This paper proposes an infrared temperature measurement system based on a PbSe photoconductive sensor that enables a high quality measurement to be obtained without chopping the radiation. The main problems that arise from eliminating chopping are analysed and the solutions adopted in order to reduce their effect are described. The quality of the measurement obtained using the system is quantified for a real application and is compared with other contributions that are independent of whether radiation chopping is performed or not.
