Abstract
- We have developed a special purpose adaptor making it possible to use a commercially available high-speed camera to observe vocal fold vibrations during phonation. The camera can capture dynamic digital images at speeds of 600 or 1200 frames per second. The adaptor is equipped with a universal-type attachment and can be used with most endoscopes sold by various manufacturers. Satisfactory images can be obtained with a rigid laryngoscope even with the standard light source. The total weight of the adaptor and camera (including battery) is only 1010 g. The new system comprising the high-speed camera and the new adaptor can be purchased for about $3000 (US), while the least expensive stroboscope costs about 10 times that price, and a high-performance high-speed imaging system may cost 100 times as much. Therefore the system is both cost-effective and useful in the outpatient clinic or casualty setting, on house calls, and for the purpose of student or patient education. [ABSTRACT FROM AUTHOR]
