Recently, microfluidic devices have become widespread for counting and sorting of particles and cells. Particles dispersed in the fluid flowing through the channel are studied using an optical microscope and a camera attached to it to develop a microfluidic device with such functions. However, it is typical for optical microscope objective lenses to be aligned in a vertical direction while obtaining images. As a result, while the particle distribution in the channel width direction is simple to analyze, the distribution in the channel depth direction requires the use of a costly specific approach such as holography. In this work, after installing two objective lenses with cameras attached vertically and horizontally, a system was constructed that can concurrently take images in the width and depth directions using a trigger. Using this approach, we observed how spherical particles migrate laterally in the cross-section of a squared microchannel in inertial Newtonian flow. Furthermore, we plan to show the spatial particle distribution in viscoelastic flow in the microchannel. |
