Summary

This article presents the design of an airborne hyperspectral imaging lidar receiving system that utilizes fiber array focal plane spectroscopy to achieve simultaneous acquisition of spatial (elevation) and rich spectral information for remote sensing and surveying. The system employs a transmission grating for spectral dispersion, a fiber array for coupling specific wavelengths to corresponding detectors, and considers different scanning methods to achieve comprehensive ground coverage. The design aims to overcome limitations of traditional methods by enabling all-weather spectral detection and improving the precision of identifying ground objects. The article discusses the system's basic principles, parameter design, simulation, and the design of the focal plane spectroscopy system, including the use of microlenses to enhance coupling efficiency. Ultimately, this technology aims to advance the capabilities of lidar in remote sensing and surveying by integrating high-resolution spatial and spectral data acquisition.
