Optical Beam Deflectors

Optical Beam Deflectors

Optical beam deflectors are devices that are used to redirect the path of a light beam. These devices are commonly used in a variety of applications, including laser scanning, optical communication systems, and imaging systems. Optical beam deflectors can be classified into two main categories: mechanical deflectors and non-mechanical deflectors. Mechanical deflectors are devices that use mechanical motion to deflect the path of a light beam. These devices typically consist of a moving mirror or prism that is controlled by a motor or other actuator. The mirror or prism is positioned at an angle to the incoming light beam, and as it moves, it deflects the beam in a different direction. Mechanical deflectors can be very precise and are often used in applications that require high accuracy. Non-mechanical deflectors, on the other hand, use non-mechanical means to deflect the path of a light beam. One common type of non-mechanical deflector is the acousto-optic deflector, which uses sound waves to change the refractive index of a material, causing the light beam to be deflected. Another type of non-mechanical deflector is the electro-optic deflector, which uses an electric field to change the refractive index of a material. Optical beam deflectors are used in a wide range of applications, including laser scanning microscopy, optical coherence tomography, and laser printing. They are also used in telecommunications systems to switch the path of light signals between different channels.
