Thermal infrared hyperspectral camera | SIMTRUM Photonics Store

The core of hyperspectral imaging is to obtain the reflection information of the target object at different wavelengths. Under low-light conditions, an external light source is required for illumination. Meanwhile, external light source illumination can provide more uniform and stable light, avoiding the dark differences and spectral distortion of the image caused by uneven illumination. The lighting source can be selected as: halogen lamp /LED light source

The function of a reflectance board is to provide a calibration reference for hyperspectral data, ensuring the accuracy and traceability of spectral reflectance data.Since there are usually certain differences in reflectance measured by different devices and at different times, after calibration with a reflectance board, the spectral data of the same target collected by different cameras/times can be directly compared. That is: The function of the reflectance board is to enable the quantification of hyperspectral data.
