Spectral imaging technology is gaining much attention in the academic development among many modern countries. Its advantage is to improve the color analysis capability of each image pixel by recording more the R, G, B signals commonly seen in digital camera. The spectral reflectance characteristics of the object is recorded. However, how accurate is the spectral signals? This research explores the stability of a multi-spectral imaging system while using different scanning speed. The results will provide a good reference for multispectral imaging.
