Synthetic Aperture Sonar Can Help Navy Hunt Sea Mines

Since World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other means of attack combined, according to a Navy report on mine warfare. New sonar research being performed by the Georgia Tech Research Institute (GTRI) could improve the Navy’s ability to find sea mines deep under water.

Imaging Space System Architectures Using a Granular Medium as a Primary Concentrator

Higher-resolution optics provide improved hyperspectral imaging for ocean and land monitoring, as well as exoplanet detection. NASA’s Jet Propulsion Laboratory, Pasadena, California Typically, the cost of a space observatory is driven by the size and mass of the primary aperture. Generally, a monolithic aperture is much heavier and complex to fabricate (hence, more costly) than an aperture of the same size but composed of much smaller units. Formation flying technology, as applied to swarm systems in space, is an emerging discipline.

Blurring the Boundaries: IP and Machine Vision Cameras Converge

In modern production facilities, users are more frequently combining two different strands of camera technology. Classic machine vision cameras manage inspection tasks and yield management, while network cameras (also called IP cameras) handle process monitoring and bringing production to a standstill when necessary.

Defining the Smart Camera

Smart cameras have been used in industrial applications for roughly two and a half decades, but advances in processor technologies have made the devices much more accessible and popular within the past 7 years, especially in areas such as machine vision and surveillance. However, when the term smart camera is mentioned, a wide variety of ideas still come to mind among individuals because there is no widespread agreement upon the definition of what a smart camera technically is. It is generally agreed upon that the basics of a smart camera include not only the image sensor, but also some type of processing chip: a CPU, DSP, FPGA, or other type of processing device (see Figure 1).

Line-Scan Camera

The 3DPIXA 3D line scan color camera from Chromasens (Burlington, MA) employs factory-calibrated stereo engineering. To output both color images and 3D altitude data in real time, the Chromasens 3DPIXA simultaneously captures two images of the same object. Height and shape are calculated using special algorithms running on the GPU.

Frame Grabbers

The PIXCI® EB1mini frame grabber from EPIX (Buffalo Grove, IL) captures from any base Camera Link device. The frame grabber includes trigger input, strobe output, shutter control, bit-packing capability, 64 bit memory addressing, and video rate sequence capture. The XCAP-Lite imaging program, provided with the PIXCI® EB1mini, provides control of image capture, as well as all board functions, through the Capture & Adjust Dialog.

X-Ray CCD Cameras

Andor Technology (Belfast, UK) has announced the iKon-M SY and Newton SY series of CCD cameras. The ‘standalone’ detectors offer -100°C deep cooling, optimized for the soft X-ray region. The 200-micron-thick Beryllium window blocks unwanted lower energies and visible wavelengths, with minimal beam hardening. The detectors are integrated and supported in a range of third-party software using Andor’s SDK, including MAT-Lab, LABView, and EPICs.

Camera Link Selector

The CLM-602 Camera Link Multiplexer from Vivid Engineering (Shrewsbury, MA) interfaces two Camera Link cameras of any configuration (base, medium, full, 80-bit) to one frame grabber. The CLM-602 incorporates high-speed (85 MHz) interfaces. Multiple camera selection methods are provided, including rear-panel switch settings, Camera Link interface signals (serial or camera control), and an external RS-232 port. The selector is housed in a sturdy, compact aluminum enclosure.

Creating Better Thermal-Imaging Lens From Waste Sulfur

Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found. The team successfully took thermal images of a person through a piece of the new plastic. By contrast, taking a picture taken through the plastic often used for ordinary lenses does not show a person’s body heat.
