ABSTRACT:
An optical pickup which performs the function of a light pen is capable of point detection of elastic waves propagated by electrochemical transducers in a direction parallel to the surface of a writing table. The table is constituted by a plate of refractive material placed within an optical polarizing cell which prevents emergence of incident radiation produced by a light source. The pickup receives that portion of the radiation which emerges from the cell by virtue of the birefringence induced within the plate by the elastic wave trains issuing from the transducers.
