Measurements of threshold illumination levels for detection of retinally non-localised moving targets show that detection of a moving target is influenced by both the spatial and the temporal modulation of the background field. The temporal response characteristics obtained from these measurements are similar to those obtained from experiments on detection of temporal flicker. Experiments with spatially modulated background fields reveal visual mechanisms with spatial properties which are essentially independent of many stimulus parameters. The response amplitude of the spatial filter which characterises these mechanisms increases linearly as a function of background contrast and is independent of the relative orientation between the background structure and the direction of target movement. These properties are used to compute the two-dimensional spatial characteristics of mechanisms involved in the detection of moving targets.
对视网膜非定位移动目标检测的阈值光照水平测量表明，移动目标的检测受背景场的空间和时间调制影响。从这些测量中获得的时间响应特性与从时间闪烁检测实验中获得的特性相似。对空间调制背景场的实验揭示了具有空间特性的视觉机制，这些特性基本上与许多刺激参数无关。表征这些机制的空间滤波器的响应幅度随背景对比度呈线性增加，且与背景结构和目标运动方向之间的相对方向无关。这些特性用于计算参与移动目标检测的机制的二维空间特征。
