Paper Abstract
The vibration analysis of vocal cords gives information about the functioning of speech organs as well as about some illness within human organism. The analysis is usually performed by electroglottography or stroboscopic methods. The authors present the new opto-mechanical and electronic system of photolaryngoscope. The instrument uses laser diode light for illumination of vocal cords. The light reflected from the vibrating cord surface is detected electronically and analyzed. The further mathematical analysis of glottograms by autoregression method with covariance or by periodogram method is performed in order to define new criteria for medical interpretation of results.
