说明与光源的视在位置和实际位置相关的事件的时空坐标
Illustrating the space-time coordinates of the events associated with the apparent and the actual position of a light source
摘要：
我们提出了一个时空图，显示在真值的时空坐标的事件与表观和实际位置的点，如源移动的恒定速度。我们使用它来构造移动发光轮廓的实际形状，或者确定表观距离和实际距离之间的关系。我们证明了光以有限速度传播的简单事实具有重要的结果，如“长度收缩”或“长度膨胀”，这种效应对源相对于位于惯性参考系原点的观察者的“接近”和“后退”特性敏感
英文摘要：
We present a space-time diagram that displays in true values the space- time coordinates of events associated with the apparent and actual positions of a point like source moving with constant velocity. We use it in order to construct the actual shape of a moving luminous profile or to determine the relationship between apparent and actual distances. We show that the simple fact that light propagates at finite speed has important consequences like "length contraction" or "length dilation" the effects being sensitive against the "approaching" and the "receding" character of the source relative to an observer located at the origin of the inertial reference frame
