Shutter with blades position feedback for astronomical camera

I will present a the topic of my Master Thesis, which is a project of a astronomical camera shutter. Shutter will be used in a camera for space surveillance and tracking (SST) and Near-earth objects (NEO) application.

Space Surveillance and Tracking is field of study that detect and predict the movement of space debris in orbit around the Earth. Near-Earth objects detection is a field of science that try to predict a potentially hit of asteroids or comets with earth. This field of application indicate a very restrictive timing parameters and a possibility of taking UTC time for blades opening and closing over each single pixel. Other parameters that have will be taken into consideration is Non-uniformity of CCD sensor pixel and shutter life time.
