The images show PIV and LIF results in 200μm wide micro channel. First experiment showing flow characteristics in two single-phase mixing. Second shows two phase flow characteristics of oil-water mixed measurement. Laser used for the experiment was double pulse 532 nm Nd:YAG solid-state pulsed laser, 350 mj × 2; 15hz with pulse width of 6-8 ns. 5 megapizel camera with the maximum sampling rate of 15Hz using double exposure mode with Epix EB1 frame grabber and MicroPulse725 V5 synchronizer. Maximum speed of the plane was 1m/s and the special resolution was 0.475 um / pixel. Latest MicroVec 3.5 software was used for the calculations.
