We present the preliminary results of a metrological standard for fiber Bragg gratings. This device is based on well-established wavemeter concepts and allows for the a priori determination of Bragg resonances that are verifiable and accurate. Although the concept is demonstrated here with small-fringe-number samplings, the production and detection of images of 50,000 metering fringes was easily accomplished with a nonidealized imaging system. Thus, since the system is characteristically similar to a standard wavemeter, increased fringe counts produce accurate frequency counter ratios for the determination of Bragg resonances, allowing for its application as a universal metering tool for many holographic systems.
