Images formed by mirrors plane mirrors curved mirrors Concave converging Convex diverging Images formed by lenses the human eye correcting vision problems nearsightedness farsightedness. A look into how we see and what we see.. What is Light?. Light is a type of . wave. .. A . wave. is a disturbance that transfers energy from one point to another without transferring matter. . Eg. . Water waves.. Rob Brown. Head Up Display Background. Classical Optics. Waveguide Optics. Classical Optics. Waveguide Displays. Vuzix. Sony. Waveguide combiner using diffraction gratings. Light from the collimating optics is diffracted at high angles by the Input Coupler diffraction grating.. Prepared for HICIAO CDR. Author: Vern Stahlberger. Institute for Astronomy.

Geometrical optics. , or . ray optics. , describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction or "instrument", that can be used to predict the path of light.. Real-time. Rendering of Physically Based Optical Effects in Theory and Practice.

Elements. used to teach geometry for over 2000 years.. It wasn’t until the early 19. th. century that light was theorized to behave as something other than a stream of particles.. Isaac Newton proposed the particle theory of light.. Newton’s theory was used to explain the reflection and refraction of light.. Julian C. Christou, Gemini Observatory. With added figures from Andrei Tokovinin (CTIO). An AO Outline. Turbulence. Atmospheric turbulence distorts plane wave from distant object.. How does the turbulence distort the wavefront? . The LEOK-1 Optics Experiment Kit is developed for general physics education in universities and colleges It can be used to construct eight experiments covering the basic experiments in geometrical opt What is fiber optics. Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. Light = straight path. . absorbs energy as its electrons. move from a low to a high energy level.. An atom:. emits light when an electron moves from a high to a low energy level..  .  .
