Ruggedization of Imaging Lenses

Imaging lenses used in many industrial machine vision applications have special requirements beyond those of standard imaging lenses. The lenses used in factory automation, robotics, and industrial inspection have to work in specific and demanding environments, which could involve vibrations, shocks, temperature changes, and contaminants. Because of these environmental requirements, new classes of ruggedized lenses are being designed specifically to work in a multitude of different scenarios, therefore creating different types of ruggedization. There are three distinct types of ruggedization available: industrial ruggedization, ingress protection ruggedization, and stability ruggedization.

Snapshot High-resolution Hyperspectral Imaging

Traditional digital cameras are comprised of an image sensor, typically either a Charge-Coupled Device (CCD), or, more commonly Complementary Metal-Oxide Semiconductor (CMOS). In either case, these devices integrate an array of photodiodes which convert photons to current which is then integrated over time and digitized. The sensing device is agnostic to the wavelength of detected photons, as long as the energy of these photons is sufficient to create electron-hole pairs which can then be separated under an electric field.

Round Lens. Square Pixels. Accurate Images. Really?

Alens is cylindrical. It captures light in a circular plane for collection onto a rectangular digital sensor plane. This collection of photons is then transformed into electricity by smaller square pixels. Just how do these disparate shapes work together to provide usable images?

Sensors’ Role Evolves as New Wearables Emerge

Microelectromechanical system (MEMS)-based components, such as sensors and actuators, began penetrating the wearable products market about a decade ago, when the first accelerometers replaced mechanical springs in pedometers and step counters.

Lawrence Berkeley National Laboratory

In 1928, physics professor Ernest O. Lawrence left his faculty position at Yale University for a job at the University of California's Berkeley campus. While at Berkeley, Lawrence invented a unique particle accelerator called a cyclotron that would prove his hypothesis: whirling charged particles around to boost their energies then casting them toward a target is an effective way to smash open atomic nuclei. Lawrence won the 1939 Nobel Prize in physics for the cyclotron, and ushered in a new era in the study of subatomic particles.

Virtual Fabrication and Assembly Documentation

Over the years, the term “virtual” has become associated with many different domains. Virtual machines are now commonplace as a substitute for physical laptops or desktops, allowing for the emulation of computer systems. Of course, virtual reality is in the news daily as new headsets, apps, and games provide a substitute for images and sounds, allowing for the simulation of a three-dimensional environment. In the printed circuit board (PCB) space, some fabrication and assembly information such as artwork, drill, netlist, test, and component placement have been conveyed virtually to manufacturing for more than 30 years.
