Construction and Reconstruction Of Image On Hologram For Engineering Physics
Construction and Reconstruction Of Image On Hologram: Holography is a technique that enables a light field, which is generally the product of a light source scattered off objects, to be…
Basic Principle of Holography For Engineering Physics
Basic Principle of Holography: Holography is based on the principle of interference. A hologram captures the interference pattern between two or more beams of coherent light (i.e. laser light). One…
What is Holography For Engineering Physics
What is Holography For Engineering Physics: Holography is “lensless photography” in which an image is captured not as an image focused on film, but as an interference pattern at the…
Single and Multi-Mode Fibers for Engineering Physics
Single Mode Fiber Optic Cable: Single Mode fiber optic cable has a small diametral core that allows only one mode of light to propagate. Because of this, the number of…
Definition of Numerical Aperture for BTech 1st Year Physics
Definition of Numerical Aperture for BTech 1st Year Physics: sine of the maximum angle of an incident beam of some optical device, or the sine of the acceptance angle of…
Acceptance Angle and Cone of Optical Fiber for Engineering Physics
Acceptance Angle of Optical Fiber for Engineering Physics: The maximum incidence angle of a light ray which can be used for injecting light into a fiber core or waveguide is know…
Propagation Mechanism of Optical Fiber for Engineering Physics
Light propagation of Optical Fiber: Visible light extends from 380 nm (violet) to 780 nm (red). For smaller wavelengths ultra-violet radiation (UV) occurs. Longer wavelengths correspond to the infrared region…
Fundamental Ideas about Optical Fiber For Engineering Physics
Fundamental Ideas about Optical Fiber For Engineering Physics: An optical fiber is a cylindrical dielectric wave guide (nonconducting wave guide) that transmits light along its axis, by the process of…
Fiber Optics for Engineering Physics
Fiber Optics for Engineering Physics: An optical fiber or optical fiber is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of…
