Non-invasive optical system and method for continuous timely triggered measuring of blood flow parameters and determining of blood components and vol. parts (blood plasma and haematocrit) etc.

摘要

The system carries out the method so that pulsed laser diodes in the wavelength range of 400 nm to 1900 nm are used, which correspond to the specific absorption characteristics of blood components. The laser diodes are so operated in a time-multiplex method, that as well as wavelength specific measuring of the light is possible after the passage through the biological tissue, it is also possible that interference light components can be eliminated.
