Embodiment approach

[0034] The embodiment of the present invention provides a passive radiation temperature measurement device and method based on the principle of confocal reflection; the principle of radiation temperature measurement, the principle of ellipsoidal reflection and the principle of parabolic reflection are cleverly combined, and the focal points of the ellipsoid 1 and the paraboloid 10 coincide, To form a confocal reflective system, place the light source under test at another focal point of the ellipsoid 1, make the light source under test gather through the reflection of the ellipsoid 1 and emit parallel to the reflection of the parabola 10, so that the photoelectric sensor 2 can collect effective signals and pass through The data acquisition card is input into the operation processing system, and the computer records and processes the data to obtain temperature information. It has the advantages of clear area to be tested, unrestricted light source to be tested, easy to carry, an...

Abstract

The invention discloses a passive radiation temperature measurement device and method based on a confocal reflection principle. The device comprises an ellipsoid and a paraboloid, wherein a light through hole is formed in the center of the ellipsoid, and a photoelectric sensor is arranged in the position right opposite to the light through hole; the paraboloid is arranged right opposite to the light through hole, and the inner surface of the paraboloid is opposite to the inner surface of the ellipsoid; and the photoelectric sensor is connected with a computer through a data acquisition card. The reflection focusing characteristic of light in the ellipsoid and the reflection parallel characteristic of the light in the paraboloid are ingeniously combined, light rays of a light source are converged to a focus and emitted out in parallel, signal acquisition or follow-up processing is facilitated, the accuracy is improved, and errors are reduced.

Description

technical field [0001] The invention belongs to the technical field of radiation temperature measurement, and in particular relates to a passive radiation temperature measurement device and method based on the principle of confocal reflection. Background technique [0002] Accurate measurement of temperature plays an important role in industrial production, aviation and scientific research. The traditional contact temperature measurement method will interfere with the original temperature distribution to a certain extent because it needs to intervene in the measured area, and is easily limited by the material. The accuracy of temperature measurement is not high and the range is narrow. Contents of the invention [0003] The purpose of the present invention is to provide a passive radiation temperature measurement device and method based on the principle of confocal reflection, so as to solve the problems in the prior art, such as the low accuracy and narrow range of temper...
