The superior penetration afforded by the laser Doppler technique will make it the practical choice for blood flow imaging in many situations.

The new patented moorLDLS technique is a development of the conventional single collimated beam laser Doppler imaging technique to allow rapid scanning. Signal processing is the same as the moorLDI2 but is applied to 64 channels simultaneously. The system uses a line of laser projected onto the tissue and an array of 64 photodiodes that detects returning laser light scattered from the tissue. The laser line is imaged by a lens on to the linear array of photodiodes. The line is swept across the tissue to produce the blood flow image. The acquisition time for a 50 x 64 pixel image is 5 seconds.
