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.

The Advanced Land Imager Helped NASA Mission Exceed Expectations.

After more than 16 years of operation, NASA’s Earth Observing–1 (EO-1) spacecraft was decommissioned on March 30 of this year. The Advanced Land Imager (ALI) developed by MIT Lincoln Laboratory was aboard as an alternative to the land-imaging sensor that was used by the Landsat Earth-observing program.

New Products: July 2017 Photonics & Imaging Technology

Photoluminescence Spectrometer (PRIORITY)

Edinburgh Instruments (Kirkton Campus, UK) introduces the FLS1000 state-of-the-art, modular photoluminescence spectrometer. The instrument excels in both steady state and time-resolved spectroscopy. It can be configured for spectral measurements from the ultraviolet to the mid-infrared spectral range, and for lifetime measurements spanning time resolutions over 12 orders of magnitude from picoseconds to seconds. Its ultimate sensitivity for the standard water Raman measurement is >30,000:1.

Robotic Vision Keeps an Assembly Plant at Home

A major manufacturer of electromechanical products had been operating six separate indexing assembly machines, each producing one of a family of more than 75 different products at about 40 parts per minute. The machines frequently sat idle as demand fluctuated for the various products. Labor expenses were high since each machine required a dedicated operator. The manufacturer considered moving the six machines and their entire production offshore to reduce labor expenses and save floor space at its European facility.

Wide-Area Surveillance Using HD LWIR Uncooled Sensors

The effectiveness of airborne search and rescue, navigation, and situational awareness tasks is predicated on the availability of high-resolution imagery that provides pilots with a clear picture and the widest possible field of view. While the human eye is extremely high resolution with an unmatched ability to detect high-spatial-frequency (HSF) objects across a wide field of regard, human vision can easily fatigue, is subject to environmental conditions, and is vastly degraded at night.

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?

Selecting the Right Standard High-Voltage Power Supply

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.
