It has always been a challenge to keep 3D products in focus under the camera or to quickly scan various objects at different distances. Liquid lens is a new technology that has been developed to adjust the focus of the optic an easier process.

Camera sensors and new machine vision applications tend to drive parallel advances in optics, and optics suppliers must continually evolve as machine vision technologies progress.

CLHS specification 1.2 recently introduced the 25 Gbps speed along with the QSFP28, SFP28, and MPO connectors. The committee has proof of concept to achieve 50 Gbps using the same IP core, ensuring an easy transition to future speeds.

Automated quality control systems improve the manufacturing process efficiency and effectiveness while simultaneously reducing the potential for human error and boosting the final product’s overall quality — and robotics and sensors play a critical role.

In this article, we review key standards that currently exist and provide an overview on recent updates and potential changes that will impact and benefit users of machine vision technologies. We also look at the work of various organizations to understand how their standards may impact the machine vision market.

Machine vision system developers must consider data bandwidth, cable length, and other factors when choosing a camera interface.

The choice of camera data interface is a vital consideration both in traditional PC-based machine vision systems and in the increasingly important area of embedded vision.

The world of machine vision imaging is largely performance driven. We’re looking for features on a part, finding edges, gaging, etc. 

Machine vision systems consist of several component parts, including illumination, lenses, camera, image acquisition and data transfer, and image processing and measurement software.

The new standard in single-link interface speed, 10 Gigabit Ethernet (10 GigE), enables users to take full advantage of the latest generation of high-performance sensors with their higher resolution, frame rates, bit depth and dynamic range.
