Lambda Micro hyper-spectral imaging system

Overview of spectral imaging techniques ：Hyper-spectral Imaging (HSI) technology is developed on the basis of multi-spectral remote sensing technology, and integrates two traditional optical diagnosis methods, spectral analysis and optical imaging, with the characteristics of "atlas integration". Compared with traditional gray image, RGB image and multi-spectral image, hyper-spectral image has more imaging bands and higher spectral resolution. For example, RGB image only has 3 band channels, and its spectral resolution is very low. The spectral resolution of multi-spectral imaging is on the order of λ/10, while that of hyper-spectral imaging can reach the order of λ/100, as shown in Figure 1, the difference between gray image, RGB image, multi-spectral image and hyper-spectral image.

Introduction to the principle of filter spectral imaging：Filter spectral cameras use special coating technology, without the need for a spectrometer module, so that tens or hundreds of spectral bands within the spectral coverage of the target object continuous imaging. The spectral information of the measured object is also obtained while the spatial feature image of the object is obtained. Gradient film hyper-spectral camera is a nondestructive testing and analysis instrument that plates gradient films of different bands on a planar array detector and can obtain spectral and image information simultaneously and quickly by imaging the target.

Lambda Micro hyper-spectral imaging system：Different targets have different spectral characteristics, so spectral information can be used to identify the types of targets and study their states. Even objects that look similar to the naked eye can also be distinguished by spectral information. The combination of hyper-spectral imaging technology and microscopic technology can extend the detection and analysis ability of hyper-spectral technology to the microscopic field. For example, it can be used in the identification and analysis of cancer cells in the field of biomedical science, the analysis of cell structure and composition changes and the early identification of diseases in the field of agriculture, the identification of fingerprint shape features in the field of criminal investigation, and the study of food quality changes in the field of food safety. In the industrial field, it can be used for OLED display luminescence test, quantum dot dark field detection, nano-particles detection, etc.
