【 摘 要 】

In this paper, we describe a novel super resolution method for pinhole optics with variable pinholes array. The imaging system is based on super resolved time multiplexing method using variable or moving pinhole array. The improved resolution and signal to noise ratio are achieved with improved light intensity in the same exposure time, compared as in a single pinhole system. This new configuration preserves the advantages of pinhole optics while solving the resolution limitation problem and the long exposure time of such systems. The system can also be used as an addition to several existing optical systems with visible and invisible light as well as to x rays systems.
