将光具座、点燃的蜡烛、凸透镜和光屏按图1所示装好,然后将蜡烛由远移近凸透像,同时调节光屏的位置,则在光屏上依次呈现倒立放大的实像、倒立等大的实像和倒立缩小的实像。当物距小于一倍焦距时,屏上无像,但用眼睛从右向左观察凸透镜,可以看到烛焰的正立放大的虚像。这是许多学生探究凸透镜成像规律时,所归纳出的成像情况。那么,是否只有这几种像呢? The optical bench, the lighted candle, the convex lens, and the light screen are installed as shown in FIG. 1, and then the candle is moved from the far side to the convex side, and the position of the light screen is adjusted at the same time. Then the inverted zoom real image is displayed on the light screen in turn. Upside-down real images and inverted real images. When the object distance is less than one focal length, there is no image on the screen, but the convex lens is observed from right to left with the eyes, and an upright enlarged virtual image of the candle flame can be seen. This is the imaging situation that many students sum up when they investigate the law of lenticular imaging. So are there only these kinds of images?
