Shortwave Infrared (SWIR) Imaging Aids Laser Tracking, Detection

As warfare becomes more asymmetric, civilians and other non-combatants become a larger percentage of the casualties, along with unintended property damage. The military, of course, hopes to avoid these types of casualties and destruction. With advancing technologies that enable more precision from their weapons, they also need better pointing and targeting capabilities, while remaining covert. Improved targeting technologies that allow detection and identification at longer standoff distances from the designators also are needed. For instance, lasers are excellent at precision pointing, but it is important that others be able to covertly image the scene as well.

3D Laser-Scanning Sensor

Perceptron (Plymouth, MI) offers the ScanWorks® hand-held 3D laser scanner that features a scanning rate of up to 458,000 points per second and can maintain a dense point resolution of approximately 14 microns. The device projects the sensor’s field of view onto the target scanning area to visualize the best scanning strategy, and may be used on dark or highly reflective surfaces. The scanning software includes a MS Windows XP-style interface, intelligent sensor calibration, real-time point shading, and automatic exposure control. Intelligent Density Management (IDMTM) monitors incoming data and limits scan data generation in low-interest areas for faster throughput.

Evaluation and Analysis Software

FARO Technologies (Lake Mary, FL) has released version 4.0 of its family of laser-scanning software: FARO Scene, FARO Scout, FARO Scout LT, and FARO Record. The user-friendly software packages are used for viewing, administrating, calibrating, filtering, and managing large, 3D point clouds collected with the FARO Laser Scanner LS — a computerized measurement device that creates a high-resolution, 3-D, digital “photograph” by scanning everything in its 360° path as far as 76 m away. Captured data may be used to create digital models, perform evaluation and analysis of an existing model, and more.

Beam Shaper

SCHOTT North America (Elmsford, NY) offers the Beam Shaper laser technology, capable of shaping “square” light from an individual laser diode or rows of strings of laser diodes into a beam of light that has a round profile and offers homogeneous light dissemination. Two versions are available: for individual laser diodes with outputs up to 1 W, the shaper is cylindrical; for bars consisting of dozens of laser diodes with a total output of tens of watts, the unit is equipped with a paddle-shaped end that matches the geometry of the diode bar. Both versions provide an output of 90%. Wavelengths range from 400 to 1,700 nm.

Two-Axis Microgage

The Microgage 2D system from Pinpoint Laser Systems® (Newburyport, MA) measures the flatness of machinery and production equipment. The unit measures flatness of rolls, moving machinery stages, gantry systems, actuators, and moving equipment to a precision of 0.0001” and can operate over ranges of a few inches to 120’. The device operates on batteries and is machined from solid aluminum with an anodized coating. A sealed, push-button keypad and LCD display are featured.

Density Filters

Reynard Corp. (San Clemente, CA) provides Circular Variable Neutral Density (CVND) filters for use in optical systems to change light intensity from 100% to less than 0.1%. The filters are specified for linear optical density or transmission, may be sized to match the end-use, and are customizable in optical density gradient function, transmission gradient function, substrate type, and coating materials. The units can be supplied from 1.0 to 8” in diameter. Gradient coatings can be supplied from 45° to 360° of rotation.

Photomultiplier Tube

The Photonis Group (Lancaster, PA) has introduced the XP1322, a 13-mm-round photomultiplier tube featuring high gain and low noise that covers the spectral range of 270 to 650nm. The device is designed for applications such as scintillation counting, high-energy physics, life sciences, bioluminescence, and more. The unit comes with or without a matching VDN, and is also available in a photon counting grade model.
