Abstract: The invention provides in one aspect a fast digital light source tracker aboard a moving ground-based or airborne platform. The tracker consists of two rotating mirrors, a lens, an imaging camera, and a motion compensation system that provides the Euler angles of the mobile platform in real time. The tracker can be simultaneously coupled to UV-Vis and FTIR spectrometers, making it a versatile tool to measure the absorption of trace gases using the light source's incoming radiation.
