Desktop 3D Scanner

NextEngine, Santa Monica, CA, offers the Desktop 3D Scanner, a full-color multi-laser scanner that scans complex shapes for CAD and 3D design applications on the desktop. About the size of a cereal box, the scanner connects directly to a PC via USB 2.0. It operates with proprietary MultiStripe Laser Triangulation (MLT) technology that features twin arrays of four Class 1M 10-mW solid-state lasers with custom optics at a 650-nm wavelength. The scanner also features twin 3-megapixel CMOS RGB image sensors, optically synchronous RGB color texture capture, and built-in spatially diverse white-light texture illuminators. Full-color photo data is captured for each surface point, and there is no preset limit for the size of objects to be scanned. Objects larger than 5.1 x 3.8" in macro mode and 13.5 x 10.1" in wide mode can be composite-captured with supplied ScanStudio(tm) software. The unit has throughput of 50,000 processed points per second, and comes with an AutoPositioner(tm) to capture multiple surfaces of objects, and a PartGripper(tm) to secure objects during scanning.

Dr. Karen Jackson, Aerospace Engineer, Landing and Impact Research (LandIR) Facility

NASA Langley Research Center, Hampton, VA Dr. Karen JacksonIn a crash, keeping the occupants alive and uninjured is paramount. In order to study the dynamics of an impact, military and general aviation aircraft, like cars, must be tested for their ability to keep their riders safe. A part of Structural Dynamics Branch in the Research and Technology Directorate at NASA Langley, the Landing and Impact Research Facility (LandIR) tests aircraft by crashing them. Dr. Karen Jackson is part of the research team.

On-Chip Debugging Emulator (Renesas Technology America)

Renesas Technology America, Inc. (San Jose, CA) offers the E8a emulator, an onchip debugging emulator for developing embedded systems that use Renesas microcontrollers. It allows referencing and modification of memory, on-chip I/O, and memory contents while a program is being executed. The tool allows C source-level debugging to be carried out with a microcontroller in the M16C, H8/Tiny, or H8/Super Low Power series, operating at full speed in the system. The device also can be used as a programmer to load code into the internal flash memory of many Renesas microcontroller families. The programming voltage range is 1.8 to 5 V, and the unit features a clock oscillator to enable asynchronous communication in line with a microcontroller’s operating frequency. The case measures 92 × 42 × 15 mm.

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.
