Mirrors are very useful in our daily lives. They are beneficial when it comes to security. In vehicles, they allow drivers to see what is coming up behind them. They will help you see traffic around obstructions and in your garage to see how much space you have in front of and to the side of your vehicle. To have a wider field of view, convex mirrors are used instead of flat ones. Convex mirrors are usually seen on large trucks to minimize the blind spot. They are also integrated into security systems so video cameras can show more than one angle at a time.
Dentists use mouth mirrors or dental mirrors to allow indirect vision and lighting inside the mouth. The mouth mirror is not only used by dentists, engineers also use it to allow vision in tight spaces and around corners of equipment.
Mirrors can also be used to point out variations in their orientation with the sun as the light source. This technique is used over long distances and was pioneered by Native American tribes and military to transmit information between distant outposts. Military survival kits even include a mirror. It is used for rescue as it attracts the attention of search and rescue helicopters.
Large high-definition television and video projectors use microscopic mirrors as their central element. Millions of microscopic mirrors are placed on the surface of a microchip. Large mirrors are used in rear projection televisions. The light is folded by one or more mirrors to make the television compact.
Precision instruments and telescopes use first surface or front silver mirrors. The reflective surface is first placed on the front surface of the glass. Aluminum is the most used. The silver front mirrors have to be renewed from time to time to maintain their quality. Dialectical mirrors are used in scientific optical work. These are glass substrates on which diametrical materials are deposited to form an optical coating.
