1.2 Instrument parameters

Instrument model: 3D-new;

The technical indicators are: measurement accuracy is 1%; laser: single pulse energy 200mj, maximum pulse frequency 10Hz

1.3 Sample preparation

The sample has good reflectivity, and the medium transmits light. The measurement area of the device to be measured should be a transparent material to ensure laser penetration and image capture quality; CCD camera pixels are 2048×2048, so the measurement area should not be too large. In the case of ensuring particle concentration , the shooting area should be within about 150mmx 150mm. For the measurement of the liquid phase, the concentration of the tracer sample is related to the size of the laser intensity nucleus, which is approximately 0.5-1.5g/m³; for the measurement of the gas and liquid phases, in order to ensure the shooting effect, the bubbles The concentration should not be too high.
