Many endoscopic systems combine white light and NIR light via LED multiplexing in order to image tissue stained with Near Infrared (NIR) fluorescent markers such as Indocyanine Green (ICG). This can result in unnecessary in-vivo energy exposure which can cause irreversible damage to tissue. A simple, single detector system is proposed in this work comprising a single excitation channel at a wavelength of 780nm. We have demonstrated that a single 1.6 Megapixel CMOS camera with quantum efficiency of less than 30% is appropriate to capture both fluorescent and non-fluorescent landmarks at NIR wavelengths. Experimental results indicate that a LASER source generating between up to 10mW of optical power at 780nm could be considered as an alternative to LED.
