HSDI Frame Rate & Pixel Excursion Calculator

Interactive web software for high-speed digital laryngeal imaging (HSDI). It computes the feasible range of camera frame rates [f_s,min, f_s,max] and minimum peak glottal excursion (pixels) from fundamental frequency, open and speed quotients, frames per vibratory phase, and peak excursion, accounting for loss of velocity SNR when inter-frame motion falls below one pixel. A second mode gives the minimum excursion K required for a chosen frame rate. The implementation is client-side HTML and JavaScript with no server dependency; the application is distributed as a static site suitable for GitHub Pages.
