The optical conditions for measurements of(k^^→,ω) spectra and spatial distributions of plasma-waves by the Fraunhofer-diffraction method are analyzed using the general theory for the method, which takes such parameters as the spatial position, wave-width and propagating angle of a plasma-wave into account. The results have made it possible to design optical systems for measurements of plasma-waves in low to high temperature plasmas using radiations from microwave to far-infrared and infrared regions. In addition, a new technique is proposed for measurements of various parameters of plasma-waves at a single shot using a multi-beam method. Further, applications of the method for measurements of drift waves in large tokamak plasmas are discussed, taking the two-waves effect into account, which occurs by a drift wave crossing an incident beam at two places. Finally, possibilities for new developments of the method and problems to be solved are briefly described.
