What is optical engineering?
Optical Engineering is an engineering discipline that focuses on designing equipment and devices that work using light. It is based on the science of optics, the field of physics that studies the properties and behavior of the visible light and its two closest neighbors on the electromagnetic spectrum, infrared and ultravial. The practice of optical engineering is ancient and the use of mirrors, shaped and polished crystals or pure water containers for purposes such as enlargement or focus of sunlight to start fires is older than 2,000 years. In modern times, this field is important for a very wide range of technologies, including optical tools such as microscopes and binoculars, lasers and many commonly used electronic and communication devices.
Some practical optics applications can be performed using an electromagnetic radiation model based on classic physics. This is because predictions of modern quantum mechanics differ noticeably from classic mechanics only in atomic or subatomA scale or under extremely unusual conditions such as temperatures almost absolute zero. Many modern optical technologies are based on how individual photons interact with atoms and particles, where the predictions of classical mechanics will cease to be a useful approximation of reality, and therefore science of quantum optics is necessary to understand and master these phenomena. Material science is also important knowledge for optical engineering.
The design of many devices that use light to view or analyze objects involves optical engineering. Viewing tools such as binoculars, binoculars and microscopes use lenses and mirrors to enlarge images, while repair lenses for glasses and contact lenses refract incoming light to compensate for defects in the wearer's vision. Thus, their creation requires considerable scientific knowledge of how these optical components will affect incoming light. SuccessThe design of the optical lens requires an understanding of how the composition, structure and shape of the lens will affect the functioning of the optical device and how the shape and materials of the lens will affect factors such as the weight, size and distribution of the weight of the device, as well as its ability to function in different conditions.
Design of devices called spectrometers cannot be carried out without optical engineering. The spectrometer uses the properties of incoming photons to discover information about the chemical composition or other properties of the thing with which the light has been issued or interacted. Spectrometers exist in a wide range of different types and are extremely important for modern science and industry in applications ranging from mineral composition to quality control in the metalworking industry to the study of other galaxies.
Optical engineering is also Essential to fiber-optical technology that transmits information via cables using light impulses instead of electricity. Optical fibers are flexible materials that can be used JAKO wavy pipeline, materials that can lead the direction of light. They lead light as it travels by using a phenomenon called Total Internal Reflection, which keeps the light directed around the core of the fiber. The design of optical fibers requires an understanding of how refractive light is when moving by different media, along with the refractive properties of different materials. The fiber optics are essential for modern communication technologies such as phones, high -speed internet and cable TV for their huge capacity.
The design of lasers that produce narrow rays of coherent light also relies on optical engineering. Lasers work with an energetically exciting material called a profit medium until it starts to release energy in the form of photons. Design Working Laser includes knowledge of quantum properties of light and various materials that can be used as GIEL MEDIE to create photons with the properties necessary for the intended use of the laser and about how optical devices such asThey are lenses and mirrors, they can focus this light. Laser technology is widely used in modern life. It is the basis for media formats of optical disks such as CD and DVD, Lidar detection technology (detection and extent of light) and in many industrial applications.
