Abstract

We proposed an active micro-scanning super-resolution imaging method. A beam shifter is placed between the lens and the camera and change the tilt angle of the beam shifter’s glass plate to achieve lateral movement of the light. Tilting the beam shifter at a tiny angle in X and Y directions to realize any geometric scanning scheme. By collecting low-resolution image sequences with different shifts in the same scene, a super-resolution algorithm can retrieve the high-resolution. In this work, we adopted the Adaptive Regularization Parameter Tuning (APRT) method to reconstruct the object details. We design and build a prototype of the beam-shifter-based imaging system, and the experiment can demonstrate a 1.5 times imaging resolution improvement of the algorithm.
