This book is rich in content and novel in material selection. It not only systematically introduces the basic theory, but also takes into account the current development of theory and technology, and emphasizes the combination of theory and application. The second edition of the Chinese version has been appraised as 2009 excellent textbook of general higher education by the Ministry of Education. The third edition made a lot of revisions to second edition, overall characteristics of the original book, and has separated the problem solving part from the original book, and supplemented the thinking problems solving part, and has become an independent book. In preparation for the fourth edition of the Chinese version and its English version, the author also made a comprehensive revision of the third edition of the original book. In order to meet the needs of bilingual teaching in key universities, the author tries to make the contents of the Chinese version and the English version consistent, so as to facilitate students''reference.
The readers of this book are senior undergraduates and postgraduates majoring in optics, optical engineering, optoelectronics, optical information science and technology, applied physics, precision instruments, etc. It can also be used as a reference book for engineers and technicians of related majors.
本书是在普通高等教育十一五*规划教材《信息光学理论与应用》第3版的基础上修订而成的,系统地介绍了信息光学的基础理论及相关的应用。全书共10章,内容涉及二维傅里叶分析、标量衍射理论、光学成像系统的频率特性、部分相干理论、光学全息照相、空间滤波、相干光学处理、非相干光学处理，以及信息光学在计量学中的应用等。
本书内容丰富,选材新颖,既系统地介绍基础理论,又同时兼顾理论和技术的发展,并强调理论与应用的结合。《信息光学理论与应用》的第2版曾被教育部评为2009年度普通高等教育精品教材。第3版在保持原书总体特色的基础上,结合作者多年的教学实践,对第2版做了许多修订和补充,并将其中的习题解答部分从原书中剥离出来,做了适当的添加和完善,同时补充了思考题解答,独立成书。
在准备出版本书和英文版时，作者对第3版又做了全面的修订，删去了一些次要的内容，对个别章节做了适当的补充，使其更加精炼、流畅，更适合于课堂教学。同时，为了配合重点大学进行双语教学的需要，作者力图使中文第4版与英文版的全书内容一致，便于学生对照参考。
本书读者对象为光学、光学工程、光电子技术、光信息科学与技术、应用物理、精密仪器等专业的高年级本科生和研究生。本书也可供相关专业的工程技术人员参考。
