We demonstrate a simple and cheap method for phase shifting that does not need additional devices. A small beam offset at the fast scanning mirror introduces a causal phase shift which can be used for recently introduced B-scan based complex image reconstruction as well as for enhancing flow signals with resonant Doppler imaging. It can be directly implemented in any FDOCT setup without additional cost. The method is demonstrated on human skin in vivo for spectrometer based FDOCT operating at 1300nm employing a handheld scanner. The latter includes the reference arm and is equipped with a single point scanner.
