Lightguide-integrated image sensor improves optical, shutter performance
A drop-in replacement for the widely deployed OV7251 global shutter VGA sensors, the cost-effective OV7251-2B global shutter image sensor, says the company, is ideal for machine vision applications that need crisp captures of objects in motion to avoid inaccurate decisions. As these applications also typically operate in difficult lighting conditions, the OV7251-2B addresses this with a new lightguide feature that improves the angular response of light capture for better system-level optical performance.
The image sensor, says the company, is ideal for a broad range of machine vision, IoT, AR/VR, gaming, drone, barcode, and simultaneous localization and mapping (SLAM) applications where it is critical to avoid even the slightest edge blur or ghosting when capturing objects in motion. For example, when an AR/VR system performs room mapping, the headset is often in continuous motion, and sharp captures are a necessity for accurate user displays. In addition, industrial machine vision applications need to accurately capture the images of objects that are typically in motion to avoid costly mistakes.
“We are improving on our widely deployed family of global shutter VGA sensors by providing a drop-in replacement for our prior generation sensor that offers an even better level of shutter efficiency with no design changes required,” says Devang Patel, senior staff marketing manager for the security and emerging segments at OmniVision. “Additionally, our new lightguide feature improves the family’s capture capabilities with better light confinement for higher system level optical performance.”
The 3.0-micron OV7251-2B image sensor is offered in a compact form factor and provides 640 x 480 resolution at 120 fps. It also integrates a one-lane MIPI serial output interface. Samples and evaluation kits are available now.
