TECHNICAL FIELD

Aspects of the disclosure relate generally to reflectometry and more specifically, relate to a retro-reflectometer for measuring the retro-reflection of physical objects in an outdoor environment.

BACKGROUND

Reflectometry uses the reflection of waves at surfaces and interfaces to detect and characterize objects. Forms of reflectometry can be classified in several ways such as by the type of radiation used, the geometry of the wave propagation, the length scales, the method of measurement, and the application domain. Electromagnetic radiation of varying wavelengths is commonly used in reflectometry. Such applications include Light Detection and Ranging (LiDAR) systems that use the reflection of electromagnetic pulses to detect the presence and to measure the location and velocity of objects.
