title: [Oscillating light from characters on screens].
abstract: An apparatus for measuring the sharpness, the oscillation degree and the stability of characters of 8 different VDTs were developed. Furthermore the contrast of luminances between the essential surfaces was measured. The following results were observed: 2 VDTs had good ergonomic qualities, one was only sufficient and 5 VDTs had insufficient ergonomic light conditions.
