Description

technical field [0001] The invention relates to a measuring device and method for spectral characteristics of surface objects. Background technique [0002] Before the present invention, the characteristic that the spectral radiance or reflectance of the ground object changes with the wavelength is called the spectral characteristic of the ground object. The measurement of spectral characteristics of ground objects is basically divided into two categories: laboratory measurement and field measurement. At present, there are spectrophotometers, spectrometers, and spectrographs to measure the reflection spectrum characteristics of ground objects. Such instruments generally consist of collectors, spectrometers, detectors and display recorders. [0003] In order to achieve high-precision surface object spectrum measurement, it is generally necessary to use expensive and special equipment, and its operation process is often very complicated. Furthermore, most methods are usuall...
