Smart Cameras Get Smarter

How Actionable Data Drives Today’s Imaging Technology Cameras are the eyes of the modern world. The devices equip today’s cars and machines, and real-time imaging capabilities support law enforcement, businesses, and homeowners. Thus far, cameras have been just that: simple cameras, eyes without a brain. Their sole purpose has been, primarily, to output images. Nowadays, however, cameras are “smarter.” In this article, we will review how imaging technology’s ability to intelligently process data will support new insights and applications.

Delivering Industrial Reliability in Scientific Lasers

Industrial-strength design and production methodologies improve the quality and productivity of scientific lasers. Scientific laser users have long relied on state-of-the-art performance (e.g., higher peak power, shorter pulse duration, wider wavelength tuning) to achieve groundbreaking results. Unfortunately, this high performance has often been emphasized at the expense of ease-of-use and reliability. Recently, however, this paradigm has dramatically changed, and some of the latest scientific lasers — including complex ultrafast amplifiers — now deliver both cutting-edge performance and exceptional reliability. This advance is sometimes referred to as “The Industrial Revolution in Ultrafast Science.”

Machine Vision System Measures ‘Drops’ in Citrus Grove Health

A University of Florida Institute of Food and Agricultural Sciences researcher has developed a machine vision system to measure the quantity of a citrus grove’s dropped and decayed oranges. The fallen fruit provides an indication of a so-far incurable disease that has been spreading through Florida’s trees since its first appearance in the state in 2005.

Ultrasonic Piezo Motor Drives

Precision motion and nanopositioning systems specialist PI (Physik Instrumente) L.P. (Auburn, MA) recently released the smallest member in their miniature rotary stage series with ultrasonic piezo motor drives. The U-622 is joining two other high dynamics miniaturized ultrasonic rotary positioners, U-624 and U-628. Vacuum compatible versions to 10-6 hPa are available.

Frame Grabber

The FireBird Camera Link Deca board frame grabber from Active Silicon (Iver, UK) is now available in two form factors: a full-height version with front panel IO and a low-profile/half-height version. The low-profile design allows the FireBird Low Profile board to be used in small embedded PC enclosures and rack-mount cases where full-height PC cards are not suitable. A full-height bracket option is available for use in standard PC form-factor enclosures.

CMOS Cameras

SMARTEK Vision (New London, CT) offers the “twenty-nine” series of CMOS machine-vision cameras. Distributed by FRAMOS Technologies (Ottawa, Ontario, Canada), the 29 x 29- mm camera line fits GigE Vision and USB3 Vision with a high-speed sensor front-end into a miniature housing. Pixel sizes range from 5.86 μm and 3.45 μm down to 1.25 μm; sensor formats range from 1/2" to 1/3". The camera connects with C-Mount, Power-over-Ethernet (PoE), and general-purpose IOs (GPIO) via a 6-pin Hirose component.

Motorized Actuators

A new series of low-cost DC drive motors from Siskiyou Corporation (Grants Pass, OR) enables precise, hands-free adjustment of translation stages and mirror mounts, using a simple, push-button control pad. Specifically, the new 500 series actuators can replace manual screw and micrometer adjusters on Siskiyou’s crossed roller bearing linear stages, kinematic mirror mounts, and IS OGP beam steering assembly for microscopes. The hand-held controller for operating these actuators offers two preset drive speeds (0.3 mm/s and 0.1 mm/second), as well as an adjustable low speed range (from 10 μm/s to 30 μm/s). The latter enables consistent, small moves (down to 1.0 μm) with a single, short button press.

3D Imaging Laser System

The system achieves high-resolution, real-time, three-dimensional imaging using an innovative single lens system. Goddard Space Flight Center, Greenbelt, Maryland NASA’s Goddard Space Flight Center has developed a non-scanning, 3D imaging laser system that uses a simple lens system to simultaneously generate a one-dimensional or two-dimensional array of optical (light) spots to illuminate an object, surface, or image to generate a topographic profile.

Smart Image Enhancement Process

Applications include improving pilot vision, real-time digital enhancement of videos, medical imaging, and thermal and night vision for surveillance systems. Langley Research Center, Hampton, Virginia NASA’s Langley Research Center researchers have developed an automatic measurement and control method for smart image enhancement. Pilots, doctors, and photographers will benefit from this innovation that offers a new approach to image processing. Initial advantages will be seen in improved medical imaging and nighttime photography. Standard image enhancement software is unable to improve poor quality conditions such as low light, poor clarity, and fog-like conditions. The technology consists of a set of comprehensive methods that performs well across a wide range of conditions encountered in arbitrary images. Conditions include large variations in lighting, scene characteristics, and atmospheric (or underwater) turbidity variations. NASA is seeking market insights on commercialization of this new technology, and welcomes interest from potential producers, users, and licensees.
