2. Stand guidance system - Wikipedia

   en.wikipedia.org/wiki/Stand_guidance_system

   An ADB Safegate A-VDGS installed on Stand K3L at Mumbai Airport.. A stand guidance system is a system which gives information to a pilot attempting to park an aircraft at an airport stand, usually via visual methods, leading to the term Visual Docking Guidance System (VDGS) and also A-VDGS (the A standing for advanced) This allows them to remain clear of obstructions and ensures that jetways ...

3. Heliostat - Wikipedia

   en.wikipedia.org/wiki/Heliostat

   The target can be located on the same polar axis that is the mirror's primary rotation axis, or a second, stationary mirror can be used to reflect light from the polar axis toward the target, wherever that might be. This kind of mirror mount and drive is often used with solar cookers, such as Scheffler reflectors.

4. Mirror - Wikipedia

   en.wikipedia.org/wiki/Mirror

   A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...

5. Spin casting (mirrors) - Wikipedia

   en.wikipedia.org/wiki/Spin_casting_(mirrors)

   Spin casting is a technique for constructing large parabolic mirrors by using the curved surface formed by a rotating liquid (e.g. in a rotating furnace). [1] It is distinct from the spin casting or centrifugal rubber mold casting (CRMC) technique used for casting metal or plastics.

6. Dielectric mirror - Wikipedia

   en.wikipedia.org/wiki/Dielectric_mirror

   Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser.

7. Digital micromirror device - Wikipedia

   en.wikipedia.org/wiki/Digital_micromirror_device

   A DMD chip has on its surface several hundred thousand microscopic mirrors arranged in a rectangular array which correspond to the pixels in the image to be displayed. The mirrors and supporting mechanical structures are constructed using surface micromachining. [4] The mirrors can be individually rotated ±10-12°, to an on or off state.
