This paper analyzes the characteristics of interference imaging spectrum signal and its timing relationship in detail for the interference imaging spectrometer, studies the key technologies of the interference imaging spectrum data transmission system, proposes a scheme to design the output data transmission system of the interference imaging spectrometer based on the microcomputer PCI bus using CPLD technology, and introduces the circuit principle and functions realized by the system. Keywords: Interference imaging spectrum data transmission PCI bus CPLD The imaging spectrum technology developed in the 1980s is a comprehensive detection technology integrating imaging technology and spectral technology, and has broad application prospects in military and civilian fields. After the 1990s, various new types of interference imaging spectrometers were successfully developed, and the amount of their output data also increased sharply. Therefore, it is urgent to study and develop reliable data transmission and recording systems. Using the powerful data processing capabilities of computers to realize the transmission, storage, calculation or display of spectral images is one of the hot spots in the current research of imaging spectrum technology. This paper proposes a design scheme for a data transmission system based on the microcomputer PCI bus for a certain type of interference imaging spectrometer.
