针对中学凸透镜成像规律实验仪器由于烛焰光源形状对称,不能动态改变、不稳定、不细腻等不足,将其改进为LED贴片时钟光源;针对单一凸透镜焦距固定,缺乏实验对比等不足,将其改进成凸透镜转盘;针对白纸光屏不能精准量化比较实像与光源大小的关系和空间位置完全对称颠倒的关系等不足,将其改进为时钟面板形状光屏。通过这些改进,加深对凸透镜成像规律的认识和理解。 Because of the shape symmetry of the candle flame light source, can not change dynamically, instability, not delicate and so on, it is improved into LED patch clock light source. According to the fixed focal length of single convex lens and the lack of experimental contrast, Improve into a convex lens turntable; for white paper screen can not accurately quantify the relationship between the actual image and the size of the light source and the spatial position of the complete symmetry upside down relationship, etc., to improve the clock panel shape screen. Through these improvements, we can deepen our understanding and understanding of the imaging laws of convex lenses.
