  • A visible/near-infrared real-time imaging spectrometer is designed for hyperspectral imaging on the basis of an Acousto-Optic Tunable Filter (AOTF). Its operating band range is 1.3 μm, in which the visible light camera works in the 400−1000 nm band and the near-infrared camera works in 1000−1700 nm band. A Field-Programmable Gate Array (FPGA) is used as the core processing unit of the spectrometer control system. The Cameralink interface is used to collect camera data, the AOTF frequency is controlled by the serial port. Through the combination of AOTF synchronization signal and the trigger signal outside the camera, the one-to-one correspondence between a continuous image and multi-wavelength cyclic acquisition is realized. Finally, the image data is transmitted to the upper computer through the USB3.0 interface for real-time display. The field test shows that the imaging quality of the spectrometer is good and the system works stably. For images with a 1024×1024 resolution, the real-time transmission rate of the image can reach up to 120 frame/s, which meets the design requirements. In practical engineering applications, the control system has a rich interface, high reliability, flexible interface and strong expansibility.
