摘要: An optical system has been developed which can determine time‐resolved temperatures in shocked materials by measuring the spectral radiance of light emitted from shocked solid samples in the visible and near‐infrared wavelength range (0.5–1.0 μm). It can measure temperatures as low as 1500 K and has been successfully used to observe shock‐induced chemical reactions in powder samples. The high sensitivity of this radiation pyrometer can be attributed to the large angular aperture (0.06 sr), the large bandwidth per channel (up to …
