New Inspection Techniques Using Submillimeter/Far-Infrared Waves
Although spectroscopists have carried out experiments in the submillimeter/ far-infrared (SMMW/FIR) spectrum for several years, others have found it difficult to utilize this spectral region. Extending from about 50 to 1000 μm, the SMMW/FIR spectrum has not in the past offered a comprehensive group of components and technology that could be favorably compared with, say, the optical or microwave spectrum. Now this picture has changed.
