2. Retroreflective sheeting - Wikipedia

   en.wikipedia.org/wiki/Retroreflective_sheeting

   They are also used as a material to increase the scanning range of barcodes in factory settings. The sheeting consists of retroreflective glass beads, microprisms, or encapsulated lenses sealed onto a fabric or plastic substrate. Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various ...

3. Silver screen - Wikipedia

   en.wikipedia.org/wiki/Silver_screen

   Essentially, the screen only reflects the specific shades of red, green, and blue output by a trichromatic video projector, and absorbs the remainder. Therefore, the projected image is reflected normally, but other light is not. In doing so, the black level on the screen is maintained. Mostly used with digital projectors in non-commercial settings.

4. Projection screen - Wikipedia

   en.wikipedia.org/wiki/Projection_screen

   Although a projection screen cannot improve a projector's contrast level, the perceived contrast can be boosted. In an optimal viewing room, the projection screen is reflective, whereas the surroundings are not. The ambient light level is related to the overall reflectivity of the screen, as well as that of the surroundings.

5. Retroreflector - Wikipedia

   en.wikipedia.org/wiki/Retroreflector

   Barcode labels can be printed on retroreflective material to increase the range of scanning up to 50 feet. [29] In a form of 3D display; where a retro-reflective sheeting and a set of projectors is used to project stereoscopic images back to user's eye.

6. Lenticular fabric - Wikipedia

   en.wikipedia.org/wiki/Lenticular_fabric

   An example of a lenticular fabric sheet that changes from a blue background with white stars to a white background with red stars. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. [1] When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.

7. Front projection effect - Wikipedia

   en.wikipedia.org/wiki/Front_projection_effect

   Front projection—the background is projected onto a two-way mirror, which reflects the image onto a highly reflective surface. A front projection effect is an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage.
