Mirror lenses have no diaphragm; light transmission is regulated by filters built into the rear of the lens, or by varying the shutter speed. Because of its reflecting design and the different types of mirrored surfaces used to transmit the light, most mirror lenses will transmit up to a full f-stop less light to the film plane than their rated speed.  1, record 4, English, - mirror%20lens

Sensors aboard the Landsat satellites were built in a "whisk broom"(across track) configuration. In a whisk broom sensor, a mirror scans across the satellite's path, reflecting light into a single detector which collects data one pixel at a time.

Sun glint occurs when the ocean acts like a mirror, directly reflecting the sunlight to the imager of the satellite. Therefore, sun glint, like an image in a mirror, provides two kinds of information. It can help to locate the position of the sun, and its varying brightness and clarity provide information about the reflecting surface. In this way, sun glint is used to study ocean surface activity.  2, record 9, English, - sun%20glint

Detection relies entirely on echoes returned by the main rotor blades which do yield a significant Doppler effect. Experience has shown that rotor blades, whether metal or plastic, behave like mirrors in terms of reflecting electromagnetic radiation. In other words, a blade will only give a usable return to the transmitter location if it is perpendicular to line connecting blade and transmitter. At the receiver, a series of return pulses can be detected, each corresponding to the passage of a blade. By analogy with the illumination of a rotating mirror, this pulsed return pattern is known as "blade flash".  1, record 20, English, - blade%20flash

La détection repose entièrement sur les échos renvoyés par les pales du rotor principal qui, eux, présentent un effet Doppler important. L'expérience a montré que les pales, métalliques ou plastiques, se comportent vis-à-vis du rayonnement électromagnétique comme des miroirs. En d'autres termes, elles ne réfléchissent l'émission radar que si elles sont perpendiculaires à celle-ci. A la réception, on enregistre donc une série de retours de caractères impulsionnels, chacun correspondant au passage d'une pale. Par analogie avec l'illumination d'un miroir tournant, on appelle "éclairs de pale" ces retours impulsionnels.  1, record 20, French, - %C3%A9clair%20de%20pale
