It is often used with laser Doppler flowmeters. use. However, when the measurement device is applied to the field of micro-scale flow field measurement or biomedical measurement, the traditional pulsed light source appears to be large and cumbersome, and may even cause harm to living samples in some aspects; in addition, complicated maintenance costs And the high unit price also causes a load on the user's operation, so gradually there is a = replacement method in use to provide users with choices. For example, in the case of traditional measurement, the light source must be expanded into a light sheet to measure the surface flow field. Therefore, when continuous light is used to shake, most designs use rotating mirror modulation to simulate a pulsed light source. As far as the current application is used in micro-flow measurement, the general traditional method is to use two high-power pulse lasers to overlap the walking light path through the mirror group. Finally, the device forms the required lighting source, and the time interval between the two. Then == step device control. However, the disadvantages are the large required volume, high cost and difficult calibration. Therefore, the use of traditional high school sophomores has its inconvenience and deficiency.丨 Pulse transport this paper standard coffee A7 A7 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economics B7 V.
