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.

Acrylate-Based Specialty Optical Fiber Coatings for Harsh Environments

Applications of optical fibers at high temperatures and in harsh environments demand coatings sustainable under those conditions. The goal of this work was to evaluate thermal and environmental stability of a series of commercially available and in-house formulated acrylate-based coatings. Dual and single-coat fiber designs were tested. The individual formulations included non-urethane and urethane acrylates, silicone acrylates and an organic-inorganic hybrid acrylate. The “as drawn” fibers were tested for attenuation, mechanical reliability, microbend sensitivity, delamination resistance and coating stripability. Thermogravimetric analysis (TGA) was used for estimating the use temperature of the coatings. In addition, the fibers were exposed to harsh environments, including dry aging in air (150°C) and in nitrogen (250°C), autoclaving, immersion in high pressure/temperature water (up to 200°C and 2000 psi) and immersion in a hot cable gel (160°C). Based on the obtained results, the best formulations were ranked for suitability in different types of fiber application.

Boosting Machine Vision with Built-in FPGA Image Preprocessing

Since imaging processing tasks can consume major CPU resources in machine vision applications, increasing processing performance within size constraints is, accordingly, a common challenge for solution providers. The following discusses the efficacy of FPGA in addressing such performance shortcomings, presents the image processing tasks most suitable for FPGA, and compares the capabilities of CPU and FPGA in operation. A built -in FPGA image preprocessing solution supporting machine vision app lications is then presented.
