Brief

Summary
This doctoral dissertation details the design and initial testing of a novel airborne hyperspectral imaging lidar receiving system that employs fiber array focal plane spectrometry to simultaneously capture spatial elevation and spectral data (500-800nm) of ground targets from a distance of 500 meters. The research addresses the limitations of current remote sensing techniques by integrating lidar ranging for elevation and passive hyperspectral imaging for spectral information into a single system where both datasets originate from the same point. The dissertation emphasizes the multi-channel splitting and efficient coupling of wide spectrum echo signals using optical fiber array technology, and includes discussions on spectral and radiation calibration of the system. The designed system aims to enhance the accuracy of ground object detection by combining high spectral and elevation information.
