The LightWave technology utilizes optoelectronics to "see" the vibration of the string, enhancing the strings' true voice by eliminating the magnetic influence or "pull" on the metal strings. As a non-contact sensor, optics do not interact with the movement of the string. Instead, they provide a flat, even response throughout the tonal spectrum of the vibrating string, producing a sonic foundation that accurately represents the instrument and the musician. This neutrality allows the string to vibrate naturally and the result is the most powerful and responsive method of string transduction ever developed, and a sound advantage for today's music.
The optical pickup is a proprietary type of transducer which utilizes an infrared emitter and an array of photodetectors for each string. The emitter casts a shadow of the string onto the photodetectors. As the string vibrates, the size and shape of the shadow changes accordingly and modulates a current which passes through the photodetectors. This current is the basis of an analog electrical signal which represents an accurate depiction of the vibrating string.
LightWave Systems' optical pickup starts with one optical transducer assembly for each string of the instrument. The monolithic bridge design features an optical block that allows for pickup adjustment independent of the string saddle. Each monolith is made out of a moldable, sonically-ideal material known as GraphTech, and provides an unprecedented level of mechanical isolation for enhanced instrument performance.
