Abstract

Improvement of an infrared light detection and ranging (IR-lidar) system for a short range (0-1000 m) and with high resolution is studied to enhance a geometrical form factor. Theoretical modeling of Mie scattering echo signals agrees with the experimental results. Introduction of a lens in front of the detector is effective for increasing the geometrical form factor, anda significant, improvement in the received signal intensity is achieved, especially for short-range measurements around 100 m. This is useful for theIR-lidar system with a detector diameter of less than 1 mm. In the theoretical model, a ray-tracing technique was applied and a transmitting laser beam with Gaussian profile was considered for better accuracy.
