    Two of 5 RapidEye satellites RapidEye's S-band antenna. RapidEye AG was a German geospatial information provider focused on assisting in management decision-making through services based on their own Earth-observation imagery.

  3. Flicker fusion threshold - Wikipedia

    en.wikipedia.org/wiki/Flicker_fusion_threshold

    The phenomenon is caused by a light stimulus in combination with rapid eye movements (saccades) of an observer in a static environment. Similar to the stroboscopic effect, the phantom effect will also occur at similar frequency ranges. The mouse arrow is a common example [21] of the phantom array effect.

  4. REM rebound - Wikipedia

    en.wikipedia.org/wiki/REM_rebound

    REM rebound is the lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation.When people have been prevented from experiencing REM, they take less time than usual to attain the REM state. [1]

  5. Rapid serial visual presentation - Wikipedia

    en.wikipedia.org/wiki/Rapid_serial_visual...

    Rapid serial visual presentation (RSVP) is a scientific method for studying the timing of vision. In RSVP, a sequence of stimuli are shown to an observer at one location in their visual field. In RSVP, a sequence of stimuli are shown to an observer at one location in their visual field.

  6. Fixation (visual) - Wikipedia

    en.wikipedia.org/wiki/Fixation_(visual)

    Ocular drift is the fixational eye movement characterized by a smoother, slower, roaming motion of the eye when fixed on an object. The exact movement of ocular drift is often compared to Brownian motion, which is the random motion of a particle suspended in fluid as a result of its collision with the atoms and molecules that comprise that fluid.

  7. Eye movement in reading - Wikipedia

    en.wikipedia.org/wiki/Eye_movement_in_reading

    Eye tracking device is a tool created to help measure eye and head movements. The first devices for tracking eye movement took two main forms: those that relied on a mechanical connection between participant and recording instrument, and those in which light or some other form of electromagnetic energy was directed at the participant's eyes and its reflection measured and recorded.

  8. Rapid eye movement sleep - Wikipedia

    en.wikipedia.org/wiki/Rapid_eye_movement_sleep

    Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The core body and brain temperatures increase during REM sleep and skin ...

    en.wikipedia.org/wiki/Rapid_Eye_Mount_telescope

    The Rapid Eye Mount telescope (REM) is a fully automatic, 60 cm aperture telescope located at ESO's La Silla Observatory at 2,400 metres altitude on the edge of the Atacama Desert in Chile. The telescope's aim is to catch the afterglows of gamma-ray bursts (GRBs).
