Paper Abstract

Lensfree digital holographic technique can become a powerful microscopic solution by adequately adapting a super resolution(SR) method together with an advanced phase retrieval algorithm. However, it comes at the cost of acquiring multiple images as well as processing large volume of data. Here, we present a multi-height based SR technique that can maximize the signal to noise ratio and the resolution, approximately 2.5 times over the actual pixel size of an image sensor, while minimizing computational cost by utilizing the much less set of the sub-pixel shifted images compared to the conventional SR methods.
