狭义相对论中运动物体的视觉形象分析

The visual image of a moving object in special relativity

我们在点观察模型的基础上,考虑小孔成像的方法,给出了一个研究运动物体视觉形象更细致化的模型,并得到了理论计算的表达式.以正方体为例,展示了它在某一观察方向上低速、高速运动时的视觉形象,并揭示了物体靠近、远离观察者时视觉形象的不同,以及棱边弯曲的现象.

We propose a more exact model for the study of the visual image of the moving object by considering a pinhole imaging process on the base of the point observed model. We derive the exact theory formulas for the calculations. Considering the cube for instance, we show the visual images of it with low and high speeds on one observed direction. The edge of cube with high speed will be bent in the visual image. The difference between the cases of closing to observer and away from the observer is discussed.
