Abstract
Multispectral imaging is a powerful tool in remote sensing applications. Recently, a micro-arrayed narrow-band optical mosaic filter was invented and successfully fabricated to reduce the size and cost of multispectral imaging devices in order to meet the requirements for low- or mid- altitude remote sensing. Such a filter with four narrow bands is integrated with an off-shelf CCD camera, resulting in an economic and light-weight multispectral imaging camera with the capacity of producing multiple images at different center wavelengths with a single shot. The multispectral imaging camera is then integrated with a wireless transmitter and battery to produce a remote sensing multispectral imaging system. The design and some preliminary results of a prototyped multispectral imaging system with the potential for remote sensing applications with a weight of only 200 grams are reported. The prototyped multispectral imaging system eliminates the image registration procedure required by traditional multispectral imaging technologies. In addition, it has other advantages such as low cost, being light weight and compact in design.
