Our system differs from conventional videoendoscopes. Standard
methods fail at seeing through blood due to light scattering at
red blood cells, if the endoscope is inserted into blood vessels.
Similarly, sight is restricted in a foggy environment subject to
droplet density and droplet size.
In both cases, one can find remedy
by using an infrared (IR) camera. Blood becomes sufficiently transparent
in the near IR region around 1.7 µm as well as around 2.2 µm. The
visibility in blood is about 6-10 mm at a wavelength of 2.1µm.
According to our roadmap, we want to bring that device into a clinical
test to validate its functionality within 2 years. |
