    en.wikipedia.org/wiki/Adaptive_optics

    Adaptive optics (AO) is a technique of precisely deforming a mirror in order to compensate for light distortion. It is used in astronomical telescopes [ 1 ] and laser communication systems to remove the effects of atmospheric distortion , in microscopy, [ 2 ] optical fabrication [ 3 ] and in retinal imaging systems [ 4 ] to reduce optical ...

    For the aperture of each instrument there are two mirrors, M 1 and M 2. M 1 which is in the light path acts as a field mirror and is a simple sphere, while the correction of the spherical aberration is done by M 2 which is not perfectly shaped and reflects the incident light unevenly. However, the deviations have been calculated so that they ...

    Two kinematic mirror mounts, with mirrors. A mirror mount is a device that holds a mirror. [1] In optics research, these can be quite sophisticated devices, due to the need to be able to tip and tilt the mirror by controlled amounts, while still holding it in a precise position when it is not being adjusted.

  6. Light switch - Wikipedia

    en.wikipedia.org/wiki/Light_switch

    Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord. Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled ...

    en.wikipedia.org/wiki/Digital_Light_Processing

    These mirrors can be repositioned rapidly to reflect light either through the lens or onto a heat sink (called a light dump in Barco terminology). Rapidly toggling the mirror between these two orientations (essentially on and off) produces grayscales, controlled by the ratio of on-time to off-time.
