Abstract
The paper introduces self-mixing interferometry in semiconductor lasers in general, and then discusses recent advancements in the coherent THz imaging and sensing systems based on the self-mixing effect in terahertz quantum cascade lasers. Two different imaging modalities are used to illustrate the coherent nature of this sensing technique and its applications to three-dimensional surface profiling and material identification.
