Cover Story：Jia Xiaohang, Zhang Qinyuan, Yan Qinglai, et al. The study of the methods for evaluating the matching rate of capsule endoscope pixels and its resolution effectiveness[J]. Opto-Electronic Engineering, 2019, 46(1): 180112; DOI:10.12086/oee.2019.180112
Modern capsule endoscopy diagnosis is a very popular research direction in the diagnosis of digestive tract diseases. It has the advantages of convenient examination, no trauma, no lead, no pain, no cross infection and no influence on the normal work of patients. It expands the field of vision of digestive tract examination and overcomes the shortcomings of traditional insertion endoscopy, such as poor tolerance, not suitable for the elderly, infirmity and critical illness. As the optical system with aberration correction can use numerical aperture to represent the optical resolution level, the number of pixels can represent the optical resolution performance of the product.Prof. Jia Xiaohang's research team started with capsule endoscopy and devoted itself to the research of matching level and validity evaluation method of full field of view with pixel number.
