Most of the inventions which led to optical sound-on-film technology employed the use of an electric lamp, called an 'exciter', shining through a translucent waveform printed on the edge of a film strip. When the light shines through the film, it is read by a photo-sensitive material and fed through a processor which converts the photovoltaic impulse into an electrical signal that is then amplifie… WebJun 1, 2024 · Optical recording technique coupled with VSDs is a promising method to monitor the brain functions by detecting optical signal changes.
