Principles and application advantages of portable hyperspectral cameras

Portable hyperspectral camera integrates the spectral imaging technology and the processing function of hyperspectral image, which is able to obtain the spectral information and spatial information of the target, and is characterized by small size, light weight and easy to carry, which provides convenience for the research and application in various fields. This paper mainly introduces the principle and application advantages of portable hyperspectral camera.

Principles of Portable Hyperspectral Cameras

1. Introduction to the principle

Portable hyperspectral cameras utilize the absorption, reflection and emission spectral properties of matter to provide more detailed data and images by capturing and recording the spectral information of an object. The camera is capable of resolving the visible wavelengths of the spectrum as well as the infrared and ultraviolet wavelengths that are imperceptible to the human eye. Hyperspectral imaging systems can acquire spectral information of an object in different bands by continuously measuring the spectrum of the prepared bands. By analyzing these spectral data, we can obtain the spectral characteristics of the object, and then classify, identify and quantitatively analyze the object.

2. Working Mode

Hyperspectral cameras can work in instant capture mode, displaying real-time images that can visualize different spectra of an object. The camera can also work in scanning mode, by scanning different positions of the object to obtain the corresponding spectral information, which can be used to study the composition of the object and the material in a specific area.

3. Effect demonstration

The images captured by the hyperspectral camera can be displayed in iridescent colors, with each color representing specific spectral information. By observing the different color distribution patterns and light/dark variations in the image, we can obtain more detailed and accurate information about the properties of the object, material characteristics, and so on.
