Abstract

According to an optical communication method based on the time correlation imaging, the time correlation imaging is applied to the field of optical communication, an intensity modulation mode of the time correlation imaging is used for replacing an existing optical communication modulation mode, and the confidentiality and anti-interference characteristics of the time correlation imaging guaranteethe safety and the accuracy of the information transmission. In addition, a channel coding mode is further expanded, by utilizing the intensity mode of the information transmission of the time correlation imaging method, the bit information carried by the system is graded according to the intensity, and the optical communication capacity and the safety are improved. The invention further providesan optical communication system based on time correlation imaging.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to an optical communication method based on time-correlated imaging and an optical communication system thereof. Background technique [0002] With the rapid development of communication technology and the advent of the era of big data, people's demand for information resources is increasing. The demand for various information business traffic makes the optical communication system must update the transmission rate and capacity in a timely, fast and accurate manner. In order to realize a larger-capacity optical communication system, people have realized the modulation and transmission of optical communication from the aspects of frequency, polarization, time, phase, and amplitude according to different physical characteristics of light, which greatly expands the capacity and distance of transmission. [0003] Time-correlated imaging is an extension of corre...
