Abstract

The invention discloses a spectral measurement system and a measurement method. The system comprises a micro spectrometer for acquiring spectrum of a sample to be measured through an acquiring light path and performing filtering and light splitting through a filter, a standard reflecting plate for reflecting visible light spectrum energy to obtain initial spectrum information, and a mobile terminal which is provided with an LED lamp and a camera and is used for lighting the sample to be measured, obtaining the initial reference spectrum intensity, acquiring dark noise strength of a camera and the spectrum intensity of the sample to be measured, and then obtaining the spectrum reflectivity of the sample to be measured according to the initial reference spectrum intensity, the dark noise strength, and the spectrum intensity of the sample to be measured. With the adoption of the system, the spectrum data with the same standard can be acquired under any different acquiring environments, so that the measuring adaptability is improved, and moreover, the spectrum data accuracy and stability can be effectively ensured.

Description

Technical field [0001] The invention relates to the technical field of spectrometers, in particular to a spectrum measurement system and a measurement method. Background technique [0002] With the rapid development of the field of instrument science in recent years, the research of spectroscopic detection instruments has become increasingly mature, playing its unique advantages in the fields of chemistry, biology, and materials. [0003] Among the related technologies, all the ultra-large, large and medium-sized spectrometers are used in the laboratory. The spectral resolution has met the requirements, but the huge volume, harsh use conditions, and expensive prices are important factors hindering the scope of its application. The spectrometer can still only be used in the laboratory. Therefore, the miniaturization of spectrometers has become a popular research direction in the development of spectrometers. Miniature spectrometers have many advantages: simple to use, small in siz...
