Abstract
By simultaneous application of signal frequencies, d-c noise reduction bias and “supersonic” a-c bias to a variable-density light valve, it is possible to make direct recordings or electrical prints on Kodachrome with very low inter-modulation distortion. This technique permits the use of a higher transmission with a resulting increase in sound output of at least 6 db.
