Abstract
An active heterodyne detection system comprises a continuously tuneable laser source () emitting infra-red radiation, means () to split the infra-red radiation into a first part and a second part, means () to provide a frequency shift between the first part and the second part, means () to direct the first part of the infra-red radiation to a target (), means () to provide the second part of the infra-red radiation as a local oscillator, means () to collect a scattered component of the first part of the infra-red light from the target (), and means () to mix the scattered component and the local oscillator and route them to a detector () for heterodyne detection over a continuous spectral range. A method of active heterodyne detection over a continuous spectral range is also disclosed.
