"Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it."
The study of light and its interaction with matter.
Reflection and Refraction: The behavior of light at a boundary between two media is described by reflection and refraction, where the light ray is either bounced back or bent as it passes through the boundary.
Ray Optics: A simplified approach to studying optics that uses rays to represent light propagation, rather than waves.
Plane Waves and Spherical Waves: Mathematical representations of light waves that can be used to describe the behavior of light.
Interference: When two or more light waves meet, they interact in a way known as interference, which can result in the light being amplified, diminished, or redirected.
Diffraction: The bending of light waves around obstacles or through narrow openings.
Polarization: The orientation of light waves along a particular axis, which can be manipulated using polarizing filters.
Dispersion: The separation of white light into its component colors by refraction through a prism.
Optical Instruments: Devices that use light to make measurements or observations, such as lenses, mirrors, and telescopes.
Wave Optics: A more complex approach to studying optics that takes into account the wave nature of light.
Quantum Optics: The study of the interaction between light and matter at the microscopic level, using quantum mechanics.
Geometrical optics: Studies the propagation of light in terms of rays rather than waves. Focuses on the laws of reflection and refraction as well as the construction of images using lenses and mirrors.
Physical optics: Deals with the wave nature of light and how it interacts with matter including interference, diffraction, polarization, and scattering.
Electromagnetic optics: Studies the behavior of light as an electromagnetic wave including its propagation, reflection, and refraction.
Quantum optics: Deals with the behavior of light at the atomic and subatomic level, including studies of the interaction between light and matter.
Nonlinear optics: Deals with the effects of high-intensity light on matter including studies of the generation of new frequencies and the manipulation of light.
Fourier optics: Studies the manipulation of light using Fourier transforms including signal processing techniques, holography, and image formation.
Adaptive optics: Uses technology to adjust and correct for aberrations in optical systems caused by factors such as atmospheric turbulence or imperfect mirrors.
Integrated optics: Focuses on the design and fabrication of optical devices and circuits using techniques from microelectronics and nanotechnology.
X-ray optics: Deals with the behavior of X-rays, their propagation, reflection and refraction, and their interaction with matter.
Ultraviolet optics: Studies the behavior of ultraviolet light, including its propagation, reflection, and refraction, and its interaction with matter.
Infrared optics: Studies the behavior of infrared light, including its propagation, reflection, and refraction and its interaction with matter.
Laser optics: Deals with the generation, manipulation, and propagation of laser light, including applications in fields such as spectroscopy, telecommunications, and medicine.
Optical metrology: Focuses on the measurement of optical components, systems, and properties, including techniques such as interferometry and polarimetry.
Optical communication: Studies the technologies and systems used to send and receive optical signals for data transmission and telecommunications.
Optical imaging: Deals with the acquisition and processing of images using optical methods and systems, including microscopy and medical imaging.
"Optics usually describes the behaviour of visible, ultraviolet, and infrared light."
"Other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties."
"The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference."
"Historically, the ray-based model of light was developed first, followed by the wave model of light."
"Progress in electromagnetic theory in the 19th century led to the discovery that light waves were in fact electromagnetic radiation."
"Some phenomena depend on light having both wave-like and particle-like properties. Explanation of these effects requires quantum mechanics. When considering light's particle-like properties, the light is modelled as a collection of particles called 'photons'."
"Quantum optics deals with the application of quantum mechanics to optical systems."
"Optical science is relevant to and studied in many related disciplines including astronomy, various engineering fields, photography, and medicine (particularly ophthalmology and optometry, in which it is called physiological optics)."
"Practical applications of optics are found in a variety of technologies and everyday objects, including mirrors, lenses, telescopes, microscopes, lasers, and fibre optics."
