Ultraviolet enhanced electrically calibrated pyroelectric radiometer design

Electrically calibrated pyroelectric radiometer(ECPR) is a kind of high precision electrical substitution radiometer(ESR) in optical power measurement.An UV enhanced ECPR is proposed in this paper.The radiometer consists of measurement circuit,high stable optical chopper and UV enhanced pyroelectric head.The measured circuit includes both analog and digital circuits.The role of the analog circuit is to amplify,track and match the photoelectric signal;the role of the digital circuit is to measure the electric power,correct the measurement result,as well as control the whole system.The basic principle,system components,functions of ECPR and the error sources to be considered are also discussed in detail.
