Abstract

Coherent frequency domain reflectometry (CFDR)1,2 uses a light source whose frequency is linearly chirped in time and encodes target distance information onto the optical frequency domain. Continuous-wave lasers are typically used in CFDR systems as the light source and the linear-chirping in laser frequency can he achieved by using external-cavity acousto-optical frequency shifters or intra-cavity frequency timing elements.
