Hand-held measuring device and measuring method for ground object spectrometer

Abstract

The invention discloses a ground object spectrometer handheld measuring device and a measuring method thereof. The device comprises a handle, a rod body and a (gun-shaped) probe fixing device. One end of the rod body is fixed in front of the handle. The probe fixing device is fixed to the other end of the rod body. The rod body can be a telescopic rod. The rod body is hollow for placing a ground object spectrometer bare fiber. The probe fixing device comprises two gun-shaped handles. In measurement, the fiber probe is fixed in front of the gun-shaped handles. The angle of each gun-shaped handle relative to the rod body in the vertical direction is adjustable, and furthermore the angle is displayed through an angle gauge. The handle is provided with a bubble level which is used for measuring horizontal degree of a measuring rod in a measuring process. The end of the handle and the end of each gun-shaped handle are provided with anti-bending helical coils. The ground object spectrometer handheld measuring device and the measuring method thereof can realize higher convenience, high speed and higher standardization in field measurement operation of the natural object spectrometer, thereby reducing manpower consumption and improving quality of measured data.

Description

technical field [0001] The invention relates to the field of research on auxiliary measuring equipment for a ground object spectrometer, in particular to a hand-held measuring device for a ground object spectrometer and a measuring method thereof, which can be equipped with two optical fiber probes and can be measured at standardized angles. Background technique [0002] At present, the measuring devices equipped with ground object spectrometers are as follows: figure 1 As shown, including the gun-shaped handle body and the fiber optic probe, there are many problems and shortcomings in the use of this measuring device. In most cases, when conducting water surface spectral measurements, the experimental environment is carried out on board. According to the measurement specifications, using When the Dual RS dual-channel series ground object spectrometer collects water surface spectra, it is necessary to avoid the influence of object shadows and water surface debris as much ...

AI Technical Summary

Problems solved by technology

Under this measurement condition, the existing gun-shaped handles have the following disadvantages: 1) the gun-shaped handle is too short to extend the measuring probe out of the ship as far as possible to prevent the influence of white foam on the water surface, the hull itself and its shadow; 2 ) It requires at least two people to cooperate to carry out the experiment (control two handles and computer); 3) It is not easy to control the observation angle when using two probes to collect water surface and sky data at the same time, and the surveyors need to have certain observation skills High demand for knowledge and manpower and high requirements for experience and technology

[0003] In addition, due to the limitation of the height of the surveyor, it is impossible to use the gun-shaped handle to measure the canopy spectrum of relatively tall shrubs and other vegetation, and it is impossible to avoid the pollution of the surveyor and its shadow as much as possible.
