Binocular open-view instrument to measure aberrations and pupillary dynamics

Autores: Emmanuel Chirre, Pedro M. Prieto and Pablo Artal
Revista: Optics Letters
Volumen: Vol. 39
Paginas: pp. 4773-4775

ISBN: 0146-9592
We have designed and built a binocular Hartmann–Shack wave-front sensor using a single microlens array and camerafor real-time aberration measurement of both eyes in an open-view configuration. Furthermore, the use of a longwavelength (1050 nm) laser diode makes the illumination source completely invisible, so […]
