| description | An optical noise canceling device includes a first optical filter, a second optical filter, a photoelectric converter and a arithmetic unit, the first and second optical filters respectively allow the light having the wavelength of the applied optical signal and the light having the wavelength different from the applied optical signal, the photoelectric converter detects the first optical signal and the second background light, and converts the light to produce a first electrical signal proportional to the illuminance of the first optical signal and a second electrical signal proportional to the illuminance of the second background optical noise. The arithmetic unit calculates the first electrical signal and the second electrical signal to obtain an output signal proportional to the illuminance of the applied optical signal. |
