  • Photoelectric pyrometer for measuring temperature of bodies of small cross-sectional dimensions which vary with respect to optical axis of pyrometer
    Patent number: 4176952
    Abstract: Disclosure is made of a photoelectric pyrometer for measuring the temperature of bodies of small cross-sectional dimensions which vary with respect to the optical axis of the pyrometer. The pyrometer comprises, in successive arrangement, an objective, a stationary field diaphragm, a slit obturator, an aperture diaphragm, a condenser sighted at the aperture of the stationary field diaphragm, and a photoelectric converter arranged in the sharp image plane of the condenser. The light-sensitive surface of the photoelectric converter receives two trains of light pulses. One of these pulse trains is formed by the above-mentioned units, whereas the other is formed by the obturator arranged across the path of a luminous flux generated by an optical feedback radiation source. The photoelectric converter produces two trains of trapezoidal electric pulses of a variable duration and on-off ratio.
