The LDA offers a combination of video capil- laroscopy and laser Doppler measurement. The system includes a laser source (1.5 mW Laser Diode, wavelength 780 nm), focused by a micro- scope objective lens to a spot size of approxi- mately 10 mm diameter. This results in a very small sample volume, so that the velocity in capillaries of 9.8–32.1 mm diameter can be singledout. By this, almost every blood cell velocity is Fig. 2.
