RGB, Farnell, Leeds, UK), and the consensual pupil diameter measurements were recorded from the left eye with an infrared camera (wavelength = 880 nm). Sampling frequency was 25 Hz. Data were ... Because the pupil dynamic is mediated by the parasympathetic and ... WebbPortable infrared pupillometry was introduced in 1989. The technology involves flooding the eye with infrared light and then measuring the reflected image on an infrared sensor. Pupil size, along with variables of the pupillary light reflex and pupillary reflex dilation, is calculated by the instrument and displayed on a screen immediately after each time …

Webb24 juli 2013 · Infrared pupillometry Pupillometry studies were performed using a binocular pupillometer (A-1000, Neuroptics Inc, San Clemente, CA). This device uses two infrared cameras with a digital image capture rate of 30 Hz. Pupil diameter was detected by threshold detection of the dark pupil and corrected for distance from the camera. WebbWe modified the camera so that the camera sensor passed only infrared (IR) images. Glints were taken as reference points for region of interest (ROI) ...
