Abstract : A system is described for producing scattered monochromatic radiation. The system comprises a planar material having surface irregularities which are brightly illuminated by the use of a laser radiation source directed parallel to the planar surface so as to graze the surface irregularities with incident radiation. The size of the surface irregularities are designed so as to be large enough to partially scatter the incident radiation while being small enough to permit a substantial portion of the radiation to pass through. A variety of embodiments are described including an arrangement to illuminate a recognizable shape or pattern, and arrangement to illuminate fluid or other droplets disbursed upon a base surface, and arrangement to illuminate the effect of external stimuli (such as acoustic vibrations applied to the surface of the base material) and finally, a coordinate system using two nonparallel laser beams.
