ABSTRACT:
A channel counter that can count the number of given wavelength channels in a specific wavelength range in a simplified system. A channel counter comprises an acousto-optic deflector, an optical fiber for transmitting light to the acousto-optic deflector, an optical receiver for receiving light transmitted from the optical fiber and diffracted by the acousto-optic deflector, an oscillator for driving the acousto-optic deflector, a scanning circuit for time-scanning the oscillation frequency of the oscillator, and a count circuit for counting the number of peaks of an electric signal output from the optical receiver per scanning duration of the scanning circuit.
