Abstract
Ptychography is a lensless coherent imaging technique that leverages various advantages observed in other lensless coherent imaging methods, such as digital holography. These advantages include high phase sensitivity, non-contact, non-destructive imaging, wide field of view, and diffraction-limited optical resolution. The ptychography imaging approach involves obtaining a series of overlapping diffraction patterns by changing the relative positions of the illumination beam and the sample, enabling the reconstruction of the sample's complex amplitude distribution. This paper presents a novel approach utilizing a highly integrated optical cage structure, an electronically controlled mobile platform, and computer control to facilitate the instrumentation of ptychography imaging
