Paper Abstract

In this paper, we describe a novel super resolution method with variable pinholes arrays. The imaging system is based on super resolved time multiplexing method using variable and moving pinholes arrays. The improved resolution and signal to noise ratio are achieved with improved light intensity in the same exposure time, compared to imaging done with a single pinhole system. This new configuration preserves the advantages of pinhole optics while solving the resolution limitation problem and the low energetic efficiency of such system. The changeable and moving pinholes array can be realized using a DLP matrix. The system can also be used as an addition to several of existing optical systems which use visible, invisible light or even x-ray radiation.
