Design and Implementation of Embedded Software for Space Colloidal Crystals Investigation

Kossel-line diffraction method is an important way to measure the structure of crystals. Colloidal crystal is one of the hotspots on the condensed physics research. In order to obtain the diffraction image, a 473nm wavelength laser is used to irradiate samples, and then the Kossel-line image of sample is projected onto the translucent screen and recorded by charge coupled device (CCD) camera. Especially, gravity convection effects can be eliminated under microgravity environment, therefore the research of growth mechanism of colloidal crystals in the space has great scientific significance. This work is to design and implement an embedded software system with remote measuring and controlling function for space colloidal crystal investigation.
