Fluoptics combines color and fluorescence imaging

Start-up Fluoptics is working with Leti to develop a dual-mode endoscope camera head that can simultaneously capture images of structures marked with fluorescent contrast medium and surrounding tissue in natural color. This advancement will give surgeons a clear picture of cancerous tissue superimposed on a color image of the surgical site. Currently, for minimally-invasive surgery, doctors must constantly switch between the two types of images and then manually adjust.
The Fluoptics prototype boasts two CCD cameras (one monochromatic, the other color) that receive two types of light signals via a series of mirrors and filters. The acquisition frequency is 25 images per second. The main challenge is to simultaneously acquire a color signal and a fluorescence signal that is a million times less intense.
