  • Fresnel lens - Wikipedia
    A Fresnel lens ( ˈfreɪnɛl, - nəl FRAY-nel, -⁠nəl; ˈfrɛnɛl, - əl FREN-el, -⁠əl; or freɪˈnɛl fray-NEL[1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections
  • 菲涅尔方程（Fresnel Equation） - 知乎
    通过预先计算物体的基础反射率的值，我们可以对两种类型的表面使用相同的Fresnel-Schlick近似，但是如果是金属表面的话就需要对基础反射率添加色彩。 我们一般是按下面这个样子来实现的：
  • Fresnel lens | Optics, Light, Illumination | Britannica
    Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length
  • Fresnel Lens - U. S. National Park Service
    In a Fresnel lens, hundreds of pieces of specially cut glass surround a lamp bulb This design intensifies the glow from the light, focusing rays of light that would normally scatter into a single, intense beam of light, which shines out in a specific direction
  • Advantages of Fresnel Lenses - Edmund Optics
    Fresnel lenses consist of a series of concentric grooves etched into plastic Their thin, lightweight construction, availability in small as well as large sizes, and excellent light gathering ability make them useful in a variety of applications

    約略在1822年，法國物理學家奧古斯丁·菲涅爾 (Augustin Jean Fresnel)發明的薄透鏡設計方法，一般簡稱菲涅爾透鏡 (Fresnel一字中的s，在法文是不發音)；此設計初始應用於燈塔的準直透鏡，在大孔徑的需求之下，菲涅爾透鏡可以設計比傳統準直透鏡來得減薄許多
  • How do Fresnel lenses work? - Explain that Stuff
    That's why lighthouses use hollow, lightweight Fresnel lenses, which have a very distinctive "stepped" surface that bends the light as much as a thick, heavy glass lens They're named for Augustin-Jean Fresnel, (1788–1827), the French physicist who pioneered them in the early 19th century
