Abstract:
1. A pyrometer, comprising: a radiation sensor configured to measure at least a portion of a radiance signal emitted from a target medium and output a voltage that is a function of an average of the absorbed radiance signal, wherein said average is calculated based on a predetermined timeframe; an optical window disposed proximate the radiation sensor and configured to control a wavelength range of the radiance signal that reaches the radiation sensor; a reflective enclosure configured to receive the target medium therein, wherein the radiation sensor and the optical window are disposed within the reflective enclosure; an amplifier in communication with an output of the radiation sensor; and a data acquisition system in communication with an output of the amplifier, wherein the pyrometer is configured to output the temperature of the target medium, wherein the reflective enclosure has a shape of an ellipsoid of rotation, and wherein the reflective enclosure is configured to have the target medium disposed at a first focus point of the ellipsoid and the radiation sensor disposed at a second focus point of the ellipsoid.
