摘要: Two crystals, made of acousto-optical material and having their respective extraordinary axes at a predetermined angle to each other, are acoustically excited; and, in combination with polarizer an analyzer, the excited crystals permit complete transmission or rejection preselected narrow band polarized light visible/infrared wavelength region.
