Abstract

A high-resolution laser Doppler velocimeter with small measurement volume is described. This instrument uses a novel frequency shifter incorporating a moving glass prism that gives stable frequency shifts up to 7 kHz and determines the velocity measurement range, which is 0.1 to 7 mm/s. The instrument has been used to measure blood flow velocities in microvessels and results are presented that demonstrate the capabilities of the system.
