Abstract
A detectable signal is obtained from a laser Doppler flowmeter operating in the heterodyne mode with nano- and pico-second pulse laser sources. The ultrashort pulse probing may be useful for depth-dependent time-resolved laser Doppler velocity measurements of blood perfusion in biological tissues. © 1998 Society of Photo-Optical Instrumentation Engineers.
