WATER QUALITY INSPECTION SYSTEM

摘要

[Problem] To provide a practical water quality inspection system that makes it possible to rapidly measure the quantity of microorganisms included in a large volume of target water while the water is flowing through piping. [Solution] The interior of transparent piping 1 through which target water W is made to flow is irradiated with coherent light and an interference fringe of object light from within the piping 1 and reference light is captured by an imaging element 32. A data processing unit 36 reproduces an image for hologram data acquired for each of imaging cycles set in accordance with the flow rate and the width of an imaging area and performs identification and quantitative measurement of an image of microorganisms M by comparing with sample data at the time of image reproduction.
