Abstract : A novel concept of objectively determining when a centrifuge subject and subsequently, a pilot, loses peripheral vision due to the physiological effects of sustained acceleration was attempted. The approach was to modulate lights in the peripheral vision of the subject as the subject stared at a centrally fixed indicator. It was demonstrated by using a special, lock-in amplifier, that a reliable visual evoked response (VER) could be elicited in the peripheral vision of a seated subject at 1 G. The next step, determining if the technique worked on subjects under sustained acceleration was never accomplished. Reliable, non-invasive means of monitoring centrifuge subjects came available during the later staged of this research which overcame the need to demonstrate this technique on the centrifuge.
