Abstract :
In this letter, we report the feasibility study of converting an ordinary off-shelf charge-coupled device (CCD) imaging sensor into a multispectral imaging instrument, using the multispectral bruises detection as an example. The resulting handheld device is capable of producing in real-time multiple pixel-registered images centered at different wavelengths in a single exposure, thereby providing overwhelming operational convenience. The results are advantageous for the development of a handheld narrowband multispectral imaging video camera for image guided medical surgery.
