The Influence of Space Environment on Microscope Imaging System

Abstract

The process of cell culture in space is very important, but nowadays, advanced space cell culture with imaging system is absent. To develop a new space microscope imaging system, the first thing for us is to analyze the space factors work on the system. So, in this paper, how the main space environment affect imaging system is presented. Firstly, the model of imaging system is shown, and modulation transfer function (MTF) is to describe the quality of imaging. Then, the influence of atmospheric pressure change, temperature change and machine vibration on imaging system is given. And, we build a relationship model between a single factor and MTF to express the influence of space factors. In the end, the correspondence design rule is given. This will be an important technical support for design space microscope imaging system.
