Abstract

The invention discloses a near infrared spectrum analyzer for quality of an agricultural product based on a micro electro-mechanical technology. The near infrared spectrum analyzer belongs to the technical field of near infrared nondestructive detection and comprises a light splitting component of a micro electro-mechanical system, an integrating sphere, a sample cup, a microprocessor, a key input and result displaying device, and a computer data processing unit. According to the near infrared spectrum analyzer, light is split by an advanced micro electro-mechanical system, so that a near infrared spectrum apparatus is achieved to be miniaturized and microminiaturized, basic conditions for research and development of a follow-up hand-held near infrared rapid detecting apparatus for the quality of the agricultural product are created, because continuous near infrared diffuse reflection spectrum of a material is detected, thereby detecting content indexes of various components for balancing the quality of the agricultural product very conveniently. Through an integrating sphere diffuse reflection way, a light signal with information of a sample is collected and transmitted to the microprocessor to be processed.

Description

technical field [0001] The invention belongs to the technical field of near-infrared non-destructive testing, and relates to a near-infrared spectrum analyzer for agricultural product quality with a novel micro-electromechanical technology (MEMS). Background technique [0002] As a fast and efficient analytical method, near-infrared spectroscopy can perform fast and precise quantitative or qualitative analysis of various samples including gases, transparent or turbid liquids, homogenates to powders, solid materials to biological tissues, etc. . Near-infrared spectroscopy (NIR) is one of the most rapidly developing high-tech analytical techniques in the past decade. It requires less sample and does not damage the sample. It does not require chemical treatment of the sample, and can be used in a very short time of 1-2 minutes The simultaneous quantitative analysis of multiple components in a sample has the advantages of low cost, high speed, high precision, no pollution, and...
