摘要
A handheld device for rendering the signals produced by individual photons is presented in this paper. Electric pulses produced by individual photons in a photomultiplier are made audible by a small loudspeaker built into the housing. Output connectors allow the pulse signals to be displayed by an external amplifier/loudspeaker system, an oscilloscope, or to be further processed by pulse counting electronics. The device is intended to be used for lecture (or public) demonstrations of the discrete nature of light.
