A light-weight near infrared fluorescence endoscope based on a single color camera: A proof-of-concept study

Here we demonstrated a light-weight near infrared fluorescence endoscope based on a low-cost single color camera to perform real time white light and fluorescence imaging, thanks to advances in image sensors and electronically controllable LED light sources. We further explored frame interpolation to facilitate the reduction of frame rate of this endoscope system, compared to a typical dual camera based NIRF endoscope system.
