Raster-based cathode-ray tubes (CRTs) are increasingly used for stimulus presentation. While very flexible, their design based on consumer electronics can limit their value in vision research. Here their limitations of resolution in time, space, intensity and wavelength are systematically compiled. Often, ingenious ideas can circumvent such limitations for specific experiments. Some ad-hoc solutions, as well as the more general techniques of dithering and anti-aliasing, are presented.
基于光栅的阴极射线管（CRT）越来越多地用于刺激呈现。虽然它们非常灵活，但基于消费电子产品的设计可能会限制其在视觉研究中的价值。在此，系统地汇总了它们在时间、空间、强度和波长方面的分辨率限制。通常，巧妙的想法可以针对特定实验规避此类限制。还介绍了一些临时解决方案以及更通用的抖动和抗锯齿技术。
