Application Of Technology Of Fiber-optic Communication To Electro-optical Theodolite

Electro-optical theodolite is a large-scale electro-optical measure equipment for shooting range.It is used for tracking and measuring special target's information.In order to improve every kind of the function hurts and system limitation to the signal delivered taking from electro-optical theodolite slip ring, A kind of project adopting fiber-optic communication replace slip ring is proposed.In this paper.Time Division Multiplex of video and data communication signal is designed and implemented based on CPLD(Complex Programmable Logic Device).Wave Division multiplex is also done for solving single fiber and double direction transmission.The practical and feasible project is put forward for resolving optical random linker.There are five chapters in this dissertation. In the first two chapters, principally introduced are the background and current progress of the research on video and optical fiber communication.In chapter three. the design and implementation of optical fiber communication system of PAL pattern's video are emphatically expounded.And the contrastive chart of export and input is put forward. In chapter four.The project of point to point single fiber and double direction transmission of many channels analogue video and data is proposed and the design of optical fiber communication system of many channels analogue video and data is introduced in detail.The multiplexer of video's 2:1 and data's 16:1 are set forth on emphasis.
