CMOS digital pixel sensors: technology and applications

CMOS active pixel sensor technology, which is widely used these days for digital imaging, is based on analog pixels. Transition to digital pixel sensors can boost signal-to-noise ratios and enhance image quality, but can increase pixel area to dimensions that are impractical for the high-volume market of consumer electronic devices. There are two main approaches to digital pixel design. The fir...

Micro Electromechanical Sensors: Technology and Applications

Micro Electromechanical Systems (MEMS) have been proved to be outstanding tools for micromachines. The current article is intended to produce an assessment of MEMS used in a wide scale in various spheres, nearly 30 years after their initial development.Conventional sensors are now aptly supported by advanced technologies. Micro Electromechanical Sensors form a class of sensors which are sensiti...

Smart sensors: Physics, technology and applications

The semiconductor technology has advanced a rapid progress in the sensors which are heart of instrumentation systems. These days, most of the sensors are ‘smart’ in nature. In such sensors, the sensing elements and associated electronics are integrated on the same chip. Generally, silicon is preferred as sensor material because it can give a suitable physical conversion effect and can give suit...

18. Retina-Like Sensors: Motivations, Technology and Applications

Retina-like visual sensors are characterized by space-variant resolution mimicking the distribution of photoreceptors of the human retina. These sensors, like our eyes, have a central part at highest possible resolution (called fovea) and a gradually decreasing resolution in the periphery. We will present a solid-state implementation of this concept. One attractive property of space-variant ima...
