Abstract

A device for infrared (IR) spectroscopic investigation of internal surfaces of a body, for example of blood vessels, comprising an endoscope (10) with light guide means to illuminate the surfaces is characterized in that at the distal end of the light guide means there is arranged a detector (12) for detecting IR light scattered from the illuminated surface and transforming it into electric signals. For otherwise identical conditions, compared to comparable known devices, the device according to the invention offers a higher signal strength and thereby the possibility to shorten the measuring time for equal signal quality.
