Understanding the key differences between CCD and CMOS image sensor technologies will allow distinguishing advantages and limitations of each type of device and help in selecting the optimal device for a given application.

Yakov Bulayev, Hamamatsu Corp.

Since the invention of charge-coupled devices (CCDs) in the 1970s, they have dominated the area of scientific and industrial imaging applications. However, in the 1990s monolithic complementary metal-oxide semiconductor (CMOS) arrays emerged as a serious alternative to CCD image sensors. This was the result of significant improvements in silicon CMOS technology that have been technically and economically driven by digital microelectronics (microprocessors, memory devices, etc.) and applications. Until recently, CCD image sensors were the sensors of choice for most industrial and...Read full article

    machine vision
    Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
    quantum efficiency
    Quantum efficiency (QE) is a measure of the effectiveness with which a device or system, typically in the context of photonics or electronics, converts incoming photons (light) into a useful output signal or response. It is expressed as a ratio or percentage and quantifies the number of electrons or charge carriers generated in response to the incident photons. In other words, quantum efficiency provides a measure of how well a device can capture and utilize photons to produce an electric...
