Abstract

The invention provides a centering and leveling device for infrared spectrometer observation and a sample rotating method. The device comprises a base, a centering platform in the shape of a rotatingbody, and a secondary leveling platform which are arranged in sequence from bottom to top, wherein the base can make a rotary motion around a center line of the base; a plurality of secondary adjusting pieces are vertically inserted into the centering platform along an annular direction; the second adjusting pieces are rotationally connected with the centering platform, and the top ends of the second adjusting pieces are connected to the bottom end of the secondary leveling platform so as to adjust the inclination angle of the secondary leveling platform; and a centering mark corresponding toan eyepiece cross wire is arranged in the center of the top of the centering platform. When samples are observed by utilizing the device disclosed by the invention, a corresponding method is adopted for centering and leveling, observation errors can be effectively reduced and even eliminated, and the de-mixing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of thermal infrared spectroscopy of rocks, and in particular relates to a centering and leveling device and a rotating sample method for infrared spectrometer observation. Background technique [0002] Quantitative acquisition of rock mineral components is the basic premise of geological mapping, and spectral unmixing is an important means of quantitative inversion of rock mineral components in hyperspectral geological remote sensing. In the thermal infrared band (2.5-25 μm), the rock spectrum not only depends on internal determinants (mineral composition and structure), but also is affected by variable factors (porosity, surface roughness, weathering degree, stress deformation, etc.). Under the conditions of rock and mineral endmembers having exactly the same determinants and variation factors, the spectrum is a linear mixture, which makes it possible to accurately extract mineral species and abundance info...
