A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing.
Exmor R is a back-illuminated version of Sony's CMOS image sensor. [5] Exmor R was announced by Sony on 11 June 2008 and was the world's first mass-produced implementation of the back-illuminated sensor technology. [6] [non-primary source needed] Sony claims that Exmor R is approximately twice as sensitive as a normal front illuminated sensor.
Hot mirror in front of the image sensor of a DSLR. Note reddish reflection of ambient light, and teal edge of filter. A hot mirror is a specialized dielectric mirror, a dichroic filter, often employed to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass.
In a device with backside illumination, the silicon light sensor for each pixel is on the "back" side of the silicon wafer, opposite the transistors and metal wiring layers. This increases the efficiency of the sensor as compared to the traditional ("frontside illumination") technology, in which some of the light is scattered by the circuit ...
An unilluminated LCD must be lit from the front. To use ambient light, the liquid crystal itself is sandwiched between a polarization filter and a reflective surface. The mirror makes the display opaque so it cannot be illuminated from the back. Most often a light source is placed around the perimeter of the LCD. Frontlights are relatively ...
A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
