Abstract
An illuminator including an optical transmission mechanism includes a transmission-side electric circuit for forming electric signals modulated in response to information, a light source for emitting intensity-modulated light in response to the electric modulated signals, optical wavelength conversion means including fluorescent material for converting part of the intensity-modulated light into illumination light, photoelectric conversion means for receiving another part of the modulated light and converting this part into reproduced electric modulated signals and a receiving-side electric circuit for reproducing the information from the reproduced electric modulated signals.
Claims6
An illuminator including an optical transmission mechanism, comprising:
- a transmission-side electric circuit for forming electric signals modulated in response to information;
- a light source emitting intensity-modulated light in response to said electric modulated signals;
- optical wavelength conversion means including a fluorescent material for converting part of said intensity-modulated light into illumination light;
- a photodetector for receiving another part of said modulated light and converting the same into reproduced electric modulated signals;
- and
- a receiving-side electric circuit for reproducing said information from said reproduced electric modulated signals,
- wherein a filter for selectively transmitting said modulated light is provided in front of said photodetector.
