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.
While back-illuminated electron-multiplying CCD (EMCCD) cameras are optimal for purposes requiring the lowest noise and dark currents, sCMOS technology's higher pixel count and lower cost result in its use in a wide range of precision applications. sCMOS devices can capture data in a global-shutter “snapshot” mode over all the pixels or ...
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.
These sensors use one of the following pixel type technologies: FSI: frontside-illuminated.The light that reaches the photosensitive area is reduced because it needs to pass through multiple metal and dielectric layers.
While the first three generations of X-Trans sensors are front-illuminated, the fourth generation uses the principle of backside illumination. This improves noise levels and image quality. This improves noise levels and image quality.
A fact from Back-illuminated sensor appeared on Wikipedia's Main Page in the Did you know column on 17 June 2010 (check views).The text of the entry was as follows: Did you know... that the back-illuminated sensor improves on conventional digital camera sensors by moving wiring so it does not interfere with light entering the front of the detector?
The D850 is the first Nikon DSLR featuring a back-illuminated image sensor claiming overall a one-stop image quality (image noise) improvement. [5] This camera was the first full frame DSLR achieving 100 points at Dxomark. [6] The D850 also won Camera of the Year for 2017 at Imaging Resource. [7] Rear of the camera with articulating screen
