Abstract

In this paper, a transmission mode optical technique is required to achieve a super-resolved image. Basically, this technique is used for high resolution and for large field of view (FOV). The object is illuminated with deterministic mask patterns, and the object encoded information is transmitted to the sensor that is positioned at an optimum distance and records the images. A Spatial light modulator (SLM) is used as a mask and phase distribution of the SLM is changed ten times to captures ten different images. By using the angular spectrum process the captured images are backpropagated sequentially and reconstruct the super-resolved image. The use of multiple deterministic masks and Spatial Light Modulator (SLM) improved the quality of the reconstruction method.
