In the fields of industrial testing, agricultural monitoring, environmental monitoring, etc., a high-tech equipment that combines imaging technology and spectral technology is playing an increasingly important role - this isNear infrared hyperspectral camera.

It can not only obtain the two-dimensional geometric spatial information of the target being tested, but also synchronously detect the one-dimensional spectral information of the target object, realizing the unique advantage of "spectrum integration", breaking the limitations of traditional detection technology, and becoming the "golden eye" for accurate analysis in fields such as agriculture, medicine, and food.

1、 Invisible Perspective: Revealing Technical Principles

The working wavelength range of near-infrared hyperspectral cameras is 780-3000nm, which is far beyond the visible range of the human eye. This camera fully utilizes the principle of interaction between light and matter - different substances selectively absorb and emit light of specific wavelengths due to their differences in molecular structure and chemical composition.

Core working principle:

The core components of a near-infrared hyperspectral camera include a spectrometer, imaging system, data processing unit, and control system. After the light is collected, the spectrometer disperses the incident light into spectral components of different wavelengths. The imaging system captures these dispersed spectral images, and the data processing unit analyzes the spectral images to extract valuable spectral feature information.

The technical process includes five key steps: light collection, spectral dispersion, image capture, data recording, and data processing and analysis. The entire process is fast, non-contact, and able to preserve complete chemical information of the substance.
