Abstract
With the prospect of space deployment of compact heterodyne radiometers based on semiconductor laser sources for Earth observation and astronomy, a ground-based prototype laser heterodyne radiometer (LHR) has been developed using a quantum cascade laser (QCL). The LHR operates in the mid-infrared part of the spectrum and has a distributed-feedback QCL as a frequency tunable local oscillator (LO).
