Tiny but mighty, image sensors capture visual information and translate it into digital data. The technology has changed the way in which we interact with and perceive visual information across many platforms and industries.
This A3 article from TECH B2B Marketing contributor John Butler delves into recent developments in image sensor technology that have created diverse products and new opportunities across multiple industries.
These devices have mostly shifted from charge-coupled device (CCD) to complementary metal-oxide semiconductor (CMOS) technology, resulting in lower power consumption, reduced costs, and faster data rate. One main benefit of CMOS image sensors is the continuous increase in resolutions and pixel densities, primarily driven by industrial inspection systems and aerial imaging and mapping platforms. Meanwhile, consumer demand is informing the need for miniaturization, where system-on-chip (SoC) designs integrate most or all components of an electronic device onto a single chip.
Image sensor development also focuses on quality imaging in challenging lighting conditions and infrared light or heat, allowing users to identify smaller defects from larger distances. Modern sensors incorporate advanced signal processing, ideal for applications that call for low latency or real-time imaging.
On the camera front, 2D camera products enable massive data transfer and feature improvements in speed, resolution, and image quality. More manufacturers are relying on 3D imaging for applications such as quick prototyping and inspection and quality control. The technology is a mainstay in facial recognition and anti-collision systems in autonomous vehicles.
Additionally, advancements in contact image sensors (CIS) — which use a stationary light source and sensor array — make the devices suitable for document digitizing and surface inspection because they provide high-speed image acquisition and produce ultra-high-resolution images.
