Abstract
The analysis of the biomechanical properties is a key factor in disease diagnosis at an earlier stage. It has found several applications in fields such as systemic sclerosis. Optical coherence elastography (OCE) is one of the techniques which has been used to characterize the mechanical properties of the skin. We designed a two-beam OCE system with better phase stability (50 times) than a single-point measurement. This system allows for minimizing bulk tissue movement. We used a piezo transducer to excite acoustic waves in the tissue and two beams to measure the acoustic wave velocity. We measured the elasticity of different ager phantoms and skin.
