1. A system for remotely detecting emissions, the system comprising:
- a radiation source, for generating a combined beam of ultraviolet and infrared radiation that propagates along a predetermined path;
a detector module, for receiving the beam of radiation and measuring at least one parameter, indicative of the relative concentration of at least one emission constituent;
the detector module further comprising;
at least one detector to produce an output proportional to at least one characteristic of the received beam;
at least one beam director that directs the beam to the at least one detector without splitting the beam.

Abstract
A system and method for remote emissions detection that uses a composite beam of ultraviolet (UV) and infrared (IR) radiation. The composite beam is used to perform spectroscopic measurements on an emissions source plume. The composite beam is not split during detection, and may, among other things, be used to detect NOx in the emissions plume.
