Verification procedure for optical wavelength meters for communication
This procedure applies to the initial verification, subsequent verification and in-use inspection of optical wavelength meters for communication (hereinafter referred to as optical wavelength meters). The requirements for relevant metrological performance in the finalization, adjustment and prototype testing of optical wavelength meters can refer to this regulation. 2 Overview
An optical wavelength meter is a special instrument for measuring the wavelength of visible and infrared lasers used in communication equipment and instruments.
An optical wavelength meter uses a Kelson interferometer with a light path difference of more than ten meters to measure the ratio of the interference orders between the multi-beam and the measured beam at the same optical path difference, so as to know the ratio of the interference orders of the two beams. When the next interferometer arm moves in a straight line, the movement of the interference fringes is generated, which is converted into electrical pulses and counted accurately. The interference fringes at the end of the measured light are measured by the counter, and the reference interference fringes at the end of the measured light are and respectively: then the wavelength of the measured light is = mo,/n,
