摘　　要：文章从多方面论述了光与人类生活密切相关、眼睛与太阳息息相应,并论述了光,作为探测无限大和无限小世界的一种最神速最机灵的载波,为人类带来无限丰富的信息,诸如显微图像、星体图样、光谱图和衍射图.这是一篇综述文章,通今溯源,联想发挥,为全面认识光——这个遨游穿梭于宏观、微观和宇观3大世界的精灵,提供广阔的科学背景和学术视野.The close relationships between light and human life as well as eyes and the sun are fully discussed. It is fully expounded that light, as the fastest and most sensitive carrier wave to detect infinite large and infinite small objects, bringsus a wealth of information, such as microscopic images, star charts, spectra and diffraction patterns. From a scientific view and academic vision, this review paper presents a comprehensive understanding of light--a spirit that shuttles in macroscopic, microscopic and cosmoscopic world.
