Abstract

In this paper we report on the design of an optical fiber-based light receiver which is meant for replacing the conventional beam steering secondary mirror of the Newtonian telescope of a biaxial Raman lidar. The influence of using optical fibre, acting as an aperture stop of constant diameter on the geometrical compression form factor; the transitional altitude and the resulting blur disk diameter have been determined. The viability of using a commercially available optical fibre as a receiver and the associated trade-offs have been discussed. A hot-fused fibre bundle-based receiver is proposed as a potential alternative for low altitude profiling to be enabled. These theoretical investigations have formed the basis for our current experimental work aimed at the development of all fibre-based reconfigurable beam delivery systems for mobile lidars.
