<p>A system for reducing optical noise is described comprising a first transmitter having a first transmitter lens and a first optical housing with a first transmitter aperture, a first light source for emitting a first light; and a first phosphor-based layer positioned proximate to the first transmitter aperture and between the first light source and the first lens. A method for reducing optical noise between devices is described comprising generating a first light from a first light source of a first transmitter, passing the first light through a first phosphor based layer, shifting the wavelength of the first light to a first selected wavelength, emitting the shifted first light from the first transmitter, generating a second light from a second light source of a second transmitter, passing the second light through a second phosphor based layer, shifting the wavelength of the second light to a second selected wavelength, different than the first wavelength, emitting the shifted second light from the second transmitter, receiving the shifted second light at the first receiver;passing the second light through a third phosphor-based layer, shifting the wavelength of the second light to a wavelength that exceeds or substantially exceeds the detection range of first receiver, and passing the second light through the first receiver without detection.</p> |
