为了确定由光电声门图探测到的偏差所提供的声门面积功能信息与超高速摄影胶片逐帧分析所得到的信息之间的关系，从5名受试者同时获得了摄影和声门图记录。对喉部振动期间光电声门记录仪感测到的光偏差的测量产生的曲线与声带、声调和假声音域中视觉图像的摄影胶片逐帧测量得出的曲线相似。比较数据的傅立叶系数表明，两条曲线之间没有显著差异。
To determine the relationship of information on glottal area function provided by deviations sensed by the photoelectric glottograph to that derived from a frame-by-frame analysis of ultrahigh-speed photographic film, simultaneous photographic and glottographic recordings were obtained from 5 [human] subjects. The measurements of the light deviations sensed by the photoelectric glottograph during laryngeal vibrations produced curves that approximated those developed from photographic film frame-by-frame measurements of the visual image in vocal fry, modal and falsetto voice registers. The Fourier coefficients of the compared data indicated that there was no significant difference between the curves.
