Abstract ：We study the feasibility of endoscopic optical Doppler tomography with a micro-electro-mechanical system (MEMS) mirror based probe. The additional phase shifts introduced by the probe are tracked and formulated. The suppression method of the probe phase shifts is proposed and validated by fluid flow detection experiments. In vivo blood flow detection is also implemented on a hairless mouse. The velocities of the blood flow in two directions are obtained to be $-$8.1 mm/s and 6.6 mm/s, respectively.
