A fiber-optic radiometer is developed for accurate noncontact temperature measurements. Of compact and novel design, it is based on replacing the usual chopper with a simple shutter. The radiometer operates in a spectral range of 5–20 µm and uses a silver-halide IR-transmitting optical fiber. The radiometer has a temperature resolution of 0.1 °C, a time response of 200 ms, and a spatial resolution of ∼1 mm. Theory, simulation, radiometer design and construction, and examples of experimental measurements are shown. The novel radiometer can be used in diverse applications in science, medicine, and industry.
