A microfluid is an imperceptible flow whose characteristic length is less than several millimeters. Tiny flow fields like this attract lots of attention in fluid engineering and heat engineering. Particle image velocimetry (PIV) has become a popular method for measuring micro fluid. In the imperceptible flow field which micro-PIV measures, it is impossible for us to measure two dimension planes by sheet illumination. In this case, we light on the whole test section by volume illumination or epi-illumination. As a result, the trace particle position of micro-PIV in depth direction is generally identified by measurement depth. In this paper, Effect of measurement depth on micro-PlV measurement accuracy is investigated.
