Abstract

Quantitative analyses of the tympanic membrane mechanical properties are needed for better understanding of its role in detailed clinical evaluation. Optical methods like Digital Holographic Interferometry (DHI), time averaged holography and ESPI are quite promising for the investigation of biological tissues. Their demonstrated ability to detect displacement changes in quasi and real time and without contacting the sample surface under study provides relevant features, such as clinical and mechanical properties. In this research time averaged vibrations patterns are shown for fresh tympanic membrane specimens taken from post-mortem cats, and subject to acoustic stimuli in the frequency range of 485 Hz up to 10 kHz. The results may provide information about sample mechanical characteristics such as its elasticity coefficient. An important feature of this approach over other techniques previously used to study the vibrations of the tympanic membrane is that it only requires an image and less equipment to carry out the measurements. Good agreement was found between the present and past measurements from previous research work. Results show the usefulness of the method in the medical field in providing relevant data about key mechanical characteristics of biological samples.
