Key result
A monostatic fiber-optic Doppler velocimeter can potentially assess blood velocity in thin superficial vessels even with probe beam distortion caused by surface scattering.
A monostatic fiber-optic Doppler velocimeter may be feasible for assessing blood velocity in thin superficial vessels despite surface scattering.
A theoretical and experimental study is presented of a Doppler velocimeter that uses a single-mode optical fiber to transmit the probe beam and collect the signal light. The performance is discussed in two cases: (i) for negligible and (ii) for strong probe beam distortion caused by surface scattering. The results suggest that in medical use the assessment of blood velocity is possible for thin superficial vessels.

Bättig et al. (1988) studied this question. Monostatic fiber-optic Doppler velocimeter was evaluated on Performance under negligible and strong probe beam distortion. A monostatic fiber-optic Doppler velocimeter can potentially assess blood velocity in thin superficial vessels even with probe beam distortion caused by surface scattering.
