PRECISION INFRARED FIBER OPTIC RADIOMETER
A wireless portable microprocessor based two channel fiber optic radiometer designed for precision temperature measurements in the IR region has been developed. The radiometer measures the surface temperature of objects within 10-45<sup>0</sup>C with the measurement error less than 0.1<sup>0</sup>C and a time constant of 1 s. Flexible fiber optic waveguides allow temperature control in hard-to-reach places.
