Paper Abstract

Toxicity of chemical substances should be determined for protecting biological environment. A Daphnia pulex is one of the indicator organisms for searching the toxicity, because the shape is changed depending on the toxicity. Conventional method for its observation has been performed under suppression of its movement in a small thin room with an ordinary optical microscope. There had been concern of the stress for the Daphnia pulex. The digital holography having the postfocusing ability was applied to it for a freely-moving Daphnia pulex. The digital holography was given a low-coherence light source and an in-line structure toward a practical on-site use with not-clean environment and vibration disturbances.
