Application of Phase Contrast Microscopy to the Study of Marine Micro-Biota

Abstract

We present the observation of the activity of artemia, one of the popular marine micro-biota species, in free space by the application of Fourier optics imaging technique The Fourier optic imaging system is consisted by a collimated laser beam source, a Fourier spatial filter, an non-coherent IR source, and a CCD imaging system By recording the images of Anemia's motion in real life, we are able to study the fundamental patterns of anemia motion mechanism, and the response of the motion pattern to the variation of its environment. Characteristic patterns of anemia's motion, such as linear motion, spiral motion, and mating collision are observed. It is shown that the increasing of the environment temperature driving the motion of anemia's moving faster and more frequently, and still saves alive even at the environment temperature up to 38C. g
