Detection device of meteorological optical range

Abstract

The invention discloses a detection device of a meteorological optical range. A parallel light emitter (2), an emitting light intensity sampler, a light path range extender, a light receiver and a data processor (9) are placed on a light source path of the detection device, wherein a light source is a white light source (1), the parallel light emitter (2) is a Galileo telescope, the light path range extender is a simulation cabin of a meteorological optical range observation environment (3) which has a length of not less than 10 m and is equipped with a built-in turbidity meter (36), a control end of the simulation cabin (3) is electrically connected to the data processor (9), a light entry hole (31), a primary plane reflector (4), a secondary plane reflector (6), a final-stage plane reflector (5) and a light outlet hole (55) are disposed respectively on two longitudinal side walls of the simulation cabin, and the light receiver is constituted of an optical antenna (7) and an electric signal detector (8). The detection device of the meteorological optical range can realize a measurement scope of 10 m-30 km of transmission-type visibility in space of a 10 m working base line and can be widely used in detection of accuracy and consistency of measurement of a visibility meter.

Description

technical field [0001] The invention relates to a detection device, in particular to a meteorological optical line-of-sight detection device. Background technique [0002] Visibility is an index that reflects the transparency of the atmosphere. Meteorologically, it refers to the maximum horizontal distance that a person with normal eyesight can see and recognize the target from the sky background under the weather conditions at that time. It can be objectively measured and used in meteorological optical vision. Cheng said. The World Meteorological Organization (WMO) defines the meteorological optical range as the length of the atmospheric path through which the luminous flux of a parallel beam of an incandescent lamp with a color temperature of 2700K weakens to 0.05 of its initial value. [0003] In automated observations, visibility is usually represented by the meteorological optical range defined by the atmospheric horizontal transmittance. Generally speaking, the obser...

AI Technical Summary

Problems solved by technology

Although this long optical path gas detection device can increase the optical path of the absorption spectrum of the gas to be measured, it also has shortcomings. First, the length of the optical path cannot be accurately determined, and it is difficult to obtain accurate measurement results; secondly, Unable to solve the problem that the measurement limit of the transmissive visibility meter is only 10km
