使用高速相机拍摄本身不发光的物体时都离不开照明光源。事实上,高速摄影的出现与照明光源技术的发展密不可分。1851年Fox—Talbot使用闪光光源拍下了快速旋转极低的照片,第一次实现了高速摄影。反过来,高速摄影技术的飞速发展又促进了照明光源技术的发展。如今,高速摄影不仅有了热辐射光源,还有形形色色的气体放电光源;不仅有连续照明光源,还有脉冲宽度相跨几个数量级的脉冲光源;不仅有传统的非相干光源,还有了象激光器那样的相干光源。 由于使用场合不同,评价高速摄影照明光源的技术标准不尽相同,但就一般而言,下几个特性会引起高速摄影工作者关注的。
The use of high-speed camera shooting itself does not light objects are inseparable from the lighting. In fact, the emergence of high-speed photography and lighting technology is inextricably linked. In 1851, Fox-Talbot used a flash light source to take very fast and very low-speed photos, the first high-speed photography. In turn, the rapid development of high-speed photographic technology has contributed to the development of lighting technology. Today’s high-speed photography includes not only thermal radiation sources but also a wide range of gas discharge light sources; not only continuous illumination sources but also pulsed light sources of several orders of magnitude across the pulse width; not only traditional incoherent light sources but also Coherent light sources such as lasers. Due to different use occasions, the evaluation of high-speed photographic lighting source technical standards vary, but in general, the next few features will cause high-speed photography concern.
