Small, 2016 The increasing miniaturization and resolution of image sensors bring challenges to conventional optical elements such as spectral filters and polarizers, the properties of which are determined mainly by the materials used, including dye polymers. Recent developments in spectral filtering and optical manipulating techniques based on nanophotonics have ...

Review of CMOS image sensors [PDF]
Microelectronics Journal, 2006 Abstract The role of CMOS Image Sensors since their birth around the 1960s, has been changing a lot. Unlike the past, current CMOS Image Sensors are becoming competitive with regard to Charged Couple Device (CCD) technology. They offer many advantages with respect to CCD, such as lower power consumption, lower voltage operation, on-chip functionality

IEEE Transactions on Circuits and Systems for Video Technology, 1997 The development of the CMOS active pixel sensor (APS) has, for the first time, permitted large scale integration of supporting circuitry and smart camera-functions on the same chip as a high-performance image sensor. This paper reports on the demonstration of a new 128/spl times/128 CMOS APS with programmable multiresolution readout capability.
