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.
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.
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 ...
Released after α6000, this is an updated version of the α5000 with a 24.3MP sensor and on-chip phase detection, the same as the α6000 but in a compact body like the Sony NEX-3/5 line. Sony claims that it is the world's smallest interchangeable-lens camera with an APS-C-size-sensor and a built-in flash, but no electronic viewfinder.
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 ...
A Shack–Hartmann (or Hartmann–Shack) wavefront sensor (SHWFS) is an optical instrument used for characterizing an imaging system. [1] [2] It is a wavefront sensor commonly used in adaptive optics systems. It consists of an array of lenses (called lenslets) of the same focal length.
Mark III free gun reflector sight mk 9 variant. Another type of optical sight is the reflector (or "reflex") sight, a generally non-magnifying optical device that allows the user to look through a glass element and see a reflection of an illuminated aiming point or some other image superimposed on the field of view.
