具备显微镜与流速表二种性能的激光多普勒显微镜由北大应用电器研究所朝仓利光及其助手三品博达创制,使用此种装置测定青蛙的毛细血管血流取得成功。目前激光多普勒流速表在公害监视诸领域已付诸实用,对于微小区域的流速测定还处在研究阶段。美国麻省理工学院最近发表了测定人眼视网膜血流取得成功的报告,称其装置的空间分辨率为一百微米。朝仓等创制的激光多普勒显徼镜的空间分辨率为十微米,分辨率比麻省理工学院的装置高十倍左右。从八月二十五日至二十八日于丹麦哥本哈根的丹麦工业大学召开的“激光多普勒流速表会议”上,朝仓发表了现所创制的装置及其实验结果报告。
A laser Doppler microscope equipped with a microscope and a flow meter was created by Asahi Shokako Co., Ltd. and its assistant Mishina Boda, a research institute of Applied Electronics at Peking University. The device was used to determine the success of capillary blood flow in frogs. At present, the laser Doppler velocity meter has been put into practical use in the field of pollution monitoring, and the measurement of the flow velocity in a small area is still in the research stage. Massachusetts Institute of Technology recently published a report on the success of human retinal blood flow measurement, claiming that the device has a spatial resolution of 100 microns. Asakura and other laser Doppler imaging system created by the spatial resolution of 10 microns, the resolution of MIT’s device is about ten times higher. Asakura presented the report on the devices and experimental results they have created at the Laser Doppler Velocimetry Conference held at the Danish Industrial University in Copenhagen, Denmark from August 25 to August 28.
