| 摘 要： | 从点源圆孔衍射的成像原理出发,经过适当推理得到仅有场曲像点的光强和位置的计算式,进而分析探讨了基于场曲的物像间曲直面的换算原理与方法及其应用。该方法有利于光学设计中对场曲进行像差平衡与校正、光学加工中对场曲的检测与修正、数码成像时做场曲的电子校正以及虚拟测量中的曲直面换算等。

| Abstract: | Starting from the imaging principle of circular aperture diffraction irradiated by a point source, after proper reasoning, the formula of the light intensity and location of image point only with field curvature is gotten, then the princi- ples and methods of conversion and its application of curved surface and plane between object and its image based on field curvature is analyzed. Theses are conducive to aberration balance and correction for field curvature in optical design, for the detection and correction of field curvature in optical processing, the electronic correction field curvature in digital ima- ging and the conversion of curved surface and plane in virtual measurement. |
