Venous occlusion plethysmography is a clinically well-established technique for limb blood flow assessment. In this method, the measurement of volume changes following venous occlusion has been performed with a variety of methods of which the most common is the mercury strain-gauge. Temperature drift and long-term instability are problems associated with this sensor. In addition, environmental protection authorities are prohibiting the use of mercury in sensors beginning in 1993. This paper presents a fiber-optic sensor that can be used as an alternative to the mercury strain-gauge in venous occlusion plethysmography and in other force or displacement sensor applications.
