“自准”赝像及识别

置平面镜于凸透镜后,则凸透镜前焦平面上的物成像于该物平面上,即“自准”成像.满足其它条件也能成像于物平面.分析不同条件下像的形成及其特点,并给出识别自准成像的判据.

Self-aimed Pseudo -image and Its Recognition

: When a plane mirror is placed behind a complex lens an object has an image on the front focus plane.This is called a self-aimed, image. On other occasions an image can also be obtained on the object plane. This paper treats of the formation of image and its characteristics in different conditions and the criterion of how to recognize the self-aimed image.
