Abstract

Block Engineering has developed a widely tunable quantum cascade laser (QCL) spectrometer, a probe, and algorithms specific to detecting low levels of surface contamination. This paper discusses the basic technology of the QCL spectrometer both in a standoff and probe based configuration. It provides information on the algorithms and probes developed for this application. The paper compares the QCL based technique to other approaches for detecting surface contamination.
