Embedded digital phase noise analyzer for optical frequency metrology

Digital signal processing is supporting novel in-field applications of optical interferometry, such as in laser ranging and distributed acoustic sensing. While the highest performances are achieved with field-programmable gated arrays, their complexity and cost are often too high for many tasks. Her...
