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.
我们开发了一种专用适配器，使得使用市售高速相机观察发声时的声带振动成为可能。该相机能够以每秒600或1200帧的速度捕捉动态数字图像。该适配器配备了通用型附件，可与各制造商销售的大多数内窥镜配合使用。即使使用标准光源，使用刚性喉镜也能获得满意的图像。适配器和相机（包括电池）的总重量仅为1010克。由高速相机和新适配器组成的新系统售价约为3000美元（美国），而最便宜的频闪仪价格约为其10倍，高性能高速成像系统的成本可能高达其100倍。因此，该系统在门诊诊所或急诊环境、上门出诊以及用于学生或患者教育方面既经济高效又实用。
