Abstract

Fourier ptychographic microscopy (FPM) is a new imaging technology developed in recent years, which can achieve a high-resolution imaging with large field of view (FOV). In FPM, the imaging retrieval quality depends on the exact position of the LED array, and there exists position errors of LED array in practice. To obtain the accurate position, this paper proposes a method of vision assisted localization to determine the coordinates of LED array, which can provide the accurate LED ray directions for improving FPM. Additionally, a multi-resolution reference is built to settle the inconsistent FOV between the FPM system and vision assisted system. The experiments are performed to illuminate the efficiency and capability of flexible application because of no LED array aligning considered.
