In this study, we have proposed a new three-dimensional measurement method of micro-flow that combines the confocal scanner and a chromatic optics. In optical design, we succeeded in generating a chromatic aberration amount of 16.5 microns only with a combination of lenses commercially available. Then, although under a narrow wavelength range, the chromatic particle image is successfully obtained. In addition, the introduction of the LDLS (Laser-Driven Light Source) and a three-plate color camera enable noise reduction and acquisition of clear particle images. Since the development and implementation of PIV algorithm to calculate the flow velocity can't guarantee the measurement accuracy with the current chromatic particle image that has narrow wavelength range, the development and validation continues in both hardware and software.

在这项研究中，我们提出了一种新的微流三维测量方法，该方法将共焦扫描仪和色度光学相结合。在光学设计中，我们仅用市售透镜的组合就成功地产生了16.5微米的色差量。然后，在较窄的波长范围内，成功地获得了彩色粒子图像。此外，LDLS(激光驱动光源)和三片式彩色相机的引入使噪音降低和获取清晰的粒子图像成为可能。针对目前波长范围较窄的彩色粒子图像，PIV算法的开发和实现不能保证测量精度的问题，继续从硬件和软件两个方面进行开发和验证。
