Abstract

Multispectral imaging camera is an important tool for two-dimensional (2-D) and 3-D spectroscopic analysis. Rather than using an available high-end product or prototype, we propose and engineer a low-cost 3-D broad-spectral imaging module, covering blue, green, red, near infrared, and long wave infrared regions. With our own designed software, it can collect 3-D spectral images from each spectral band simultaneously and it can combine these images into 2-D and 3-D fused spectral images. It is designed in a compact 16.9×2.9×7.1 cm³ with just 310 grams.
