Micro Laser Doppler Sensor
| German title: | Mikro-Laser-Doppler Sensor | |
| Acronym: | MiLD | |
| Duration: | 1st July 2014 - 31st December 2016 | |
| Description: | The aim of the project was to develop a miniaturized, non-invasive sensor for determining the velocity of flowing fluids - in particular for use on the skin to assess the blood flow situation. The basic physical principle is based on the Doppler frequency shift of coherent laser light at the moving scattering centers of blood. As a major innovation, a sensor was developed which contains the light sources (surface emitting laser diodes - VCSEL) as well as the detectors, which avoids the disadvantages of the otherwise usual optical fiber coupling and decoupling. Demonstrators were used to perform the first in-vivo series of measurements on volunteers. To manipulate the blood flow situation, different pressures were set up with an arm cuff. Using the developed evaluation procedures, the same plausible trends could be observed for all volunteers. |
