Abstract
The design of a compact, dual-polarization, nonscanning lidar system intended to fly in a small, single-engine aircraft for airborne study of freshwater marine ecosystems and mapping of fish schools in mountain lakes is discussed. Design trade-offs are presented with special attention paid to selecting the field of view and telescope aperture diameter. Example results and a comparison with a similar existing lidar system are presented.
Highlights
Airborne lidar study of freshwater ecosystems is still a relatively unexplored field, and there are many applications in lake and river ecology, fisheries, and so forth.[1]
These lidars rely on elastic scattering, Brillouin scattering has been investigated as a method for lidar profiling of water temperature.[21,22,23,24,25]
The two initial scientific objectives for this instrument were the mapping of invasive lake trout (Salvelinus namaycush) spawning sites in Yellowstone Lake and other waters and large-scale mapping of plankton layers
Summary
Airborne lidar study of freshwater ecosystems is still a relatively unexplored field, and there are many applications in lake and river ecology, fisheries, and so forth.[1]. The purpose of this paper is to describe the design of a low-cost, compact, nonscanning lidar system for freshwater lake studies from a single-engine airplane This instrument was developed to explore the potential for lidar study of freshwater lakes throughout Montana and the Greater Yellowstone Ecosystem. The two initial scientific objectives for this instrument were the mapping of invasive lake trout (Salvelinus namaycush) spawning sites in Yellowstone Lake and other waters and large-scale mapping of plankton layers
