optical communication is a kind of communication that use light propagation to send data between two points. Free Space Optics are capable of up to 2.5 Gbps of data‚ voice and video communications through the air‚ allowing optical connectivity without requiring fiber-optic cable or securing spectrum licenses. So we can use LED’s or Laser for transmission data. Free Space Optics (FSO) technology is relatively simple. It’s built on a laser transmitter and a receiver to provide full duplex capability

range. A lens antenna consists of a lens proper and of a feed. The shape of the lens depends on the refractive index n (the ratio of the phase velocity of propagation of a radio wave in a vacuum to that in the lens). A decelerating lens antenna‚ as in optics‚ is one for which n > 1. An accelerating lens antenna (without an optical analogy) is one for which n < 1. The feed is usually a horn antenna that generates a spherical wave front or an antenna array that produces a cylindrical wave front.

Building Physics Laboratory building case study showcases the refurbishment of the southern façade with the Anidolic Ceiling system‚ achieving higher luminance and illuminance factors. The Anidolic Blinds are a façade system where the non-imaging optics prevent high solar rays but allow lower altitude diffuse light into the room. Solar Tubes or “Tubular Daylighting Devices‚” an alternative means of redirecting daylight into a space‚ where it uses some of the same principles as the Anidolic daylighting

different isotropic media‚ such as water and glass. • It’s also commonly known as ’’The Law Of Refraction’’ What is light : How is light propagated through different optic medium? • Light is the natural agent that stimulates sight and makes things visible; electromagnetic radiation from about 390 to 740 nm in wavelength. • In optics‚ Snel’s Law is used to calculate the path of waves to compute the angles of incidence and refraction. • The law is also used in metamaterials‚ which allows light

Newtonian reflecting telescope Aim: To recreate Newton’s experiment in building a reflecting telescope‚ aiming to further the field of optics. We hope to use the theory studied in this experiment and produce a working Newtonian telescope (that Newton designed). He wanted to create a telescope that was not affected by chromatic aberration and thus further the field of optics. We also aim to try to remove the problem of spherical aberration that Newton had trouble with in building his telescope. Introduction:

To find Refractive Indices of Water And Turpentine Oil using a plane mirror‚ a equiconvex lens (made from a glass of known refractive index) and an adjustable object needle APPARATUS: A convex lens‚ an optical needle‚ a plane mirror‚ a clamp stand‚ a spherometer‚ a plumb line‚ metre scale‚ water and turpentine oil Theroy : Let’s add small amount of water on a flat‚ plane surface and place a convex lens over it. This forms a plano-concave lens of water between the lower surface of convex lens and

course‚ his fingers pass through it with no tactile sensation. 2.2 Tactile Display “Airborne Ultrasound Tactile Display [Iwamoto et al. 2008]” is a tactile display which provides tactile sensation onto the user’s hand. It utilizes the nonlinear phenomenon of ultrasound; acoustic radiation pressure. When an object interrupts the propagation of ultrasound‚ a pressure field is exerted on the surface of the object. The acoustic radiation pressure P [Pa] is written as P = αE

type are parabolic reflectors‚ found in optical devices such as reflecting telescopes that need to image distant objects‚ since spherical mirror systems‚ like spherical lenses‚ suffer from spherical aberration. One advantage that mirror optics have over lens optics is that mirrors do not introduce chromatic aberration. * | Convex mirrors A convex mirror diagram showing the focus‚ focal length‚ centre of curvature‚ principal axis‚ etc. A convex mirror‚ fish eye mirror or diverging mirror‚ is
