Abstract

The invention provides a long-distance liquid transmission rate measuring device and measuring method. The measuring device sequentially comprises a light source, a first special-shaped optical prism,a sample pipe and a second special-shaped optical prism, wherein the measuring device also comprises a first precise displacement table used for moving the first special-shaped optical prism, a second precise displacement table used for moving the second special-shaped optical prism, a detection system, a movement control system and a computer, wherein the computer controls the second precise displacement table through the movement control system; the computer is also used for controlling the detection system. The device and the method have the advantages that the system structure is compact;the long-distance system liquid transmission rate test can be realized; the fast and precise change of different lengths and distances can be realized; the optical path transmission direction cannotbe easily changed; the system installation positioning and test are facilitated; the result can be fast obtained after once measurement; the light intensities of the sample pipe before sample chargingand after the sample charging do not need to be respectively measured.

Description

technical field [0001] The invention relates to an optical measurement device for liquid transmittance, in particular to a liquid transmittance measurement device for long-distance transmission. Background technique [0002] In recent years, some transparent liquids, due to their higher refractive index than air or some special ionization characteristics, have increasingly replaced air and become the carrier of experimental equipment for scientific research and experiments. [0003] In the physical experiments of particle or ray detection, some transparent liquids are used as carriers for long-distance transmission. When photons, charged particles, or rays are irradiated, the atoms or molecules in the liquid are excited or ionized, and these atoms or molecules de-excite Photons are generated during the process, usually called fluorescence, which are detected by detection equipment to indirectly detect certain properties of the incident particles or rays. The length of the s...
