  The convergence of recent advances in optical fabrication and digital
processing yields a new generation of imaging technology: light-field cameras,
which bridge the realms of applied mathematics, optics, and high-performance
computing. Herein for the first time, we introduce the paradigm of light-field
imaging into laryngoscopy. The resultant probe can image the three-dimensional
(3D) shape of vocal folds within a single camera exposure. Furthermore, to
improve the spatial resolution, we developed an image fusion algorithm,
providing a simple solution to a long-standing problem in light-field imaging.
