Abstract
Abstract An instrument for generating tone signals, by which is meant signals intended for generating sounds or musical notes, or alternatively signals for generating optical images and the like, has a radiation emitter arranged to emit radiation into an elongate emission space. A sensor is sensitive to radiation received from an elongate sensing space, which is non-coincident with the emission space. The current signals are generated in response to the sensor. Preferably, the emission sensing spaces partially overlap as a result of a different orientation of the spaces.
