Abstract

•A broadband optical pyrometer with a rise time of ∼70 ps was developed.•An improved calibration procedure and data processing method was proposed.•Deviation in the dynamic temperatures determined by the pyrometer was less than 2%.•The pyrometer can be used to measure the temperature of laser shocked matter.
