InGaAs Imaging Sensor

New Imaging Technologies (Verrières le Buisson, France) introduces the NSC1401, a new analog wide dynamic range InGaAs sensor series in 320x256 pixels (QVGA). The NSC1401 uses a new generation of ROIC with 320x256 pixels at 25um pitch coupled to an InGaAs retina that operates in WDR mode and global shutter. The spectral response range goes from 900nm to 1700nm. The analog front end is designed to achieve extremely low input noise and ultra-fast response time down to 200ns for applications such as active imaging. The sensor operates both in linear integration mode and in log response. The NSC1401 can operate without TEC within an ambient temperature range from -40°C to 70°C.

Touchscreen Controller

Quantum Composers (Bozeman, MT) has launched a new touchscreen controller for simplified control of laser systems. The all new Smart Controller is an easy to use extension for manual repair systems that may include a microscope setup and has the functionality to control the systems energy, firing mode, rate, and slit size and shape. The Smart Controller is a portable device that eliminates the need for a desktop computer to operate laser systems. An optional video module is also offered which overlays the outline of the slit shape onto standard composite or s-video signals from the system camera. This feature allows the user to clearly see where the repair area will be on the monitor before actually making cuts.

Infrared Lighting Module

Vision Components (Ettlingen, Germany) has introduced the new VC Flash infrared area lighting for OEMs. The lighting module has been developed specifically for traffic surveillance applications. Fitted with 24 high power LEDs, it ensures optimal brightness in mobile and stationary ANPR/ALPR applications, red light enforcement, access control, and toll collection without a glare effect that could endanger drivers. VC Flash illuminates an area measuring 7.5 by 5.0 m from 20 m away. The module measures 195 x 80 x 20 mm, and operates with a central wavelength of 850 nm and a spectral width of 30 nm. Power consumption peaks at 36 W for the highest pulse duration and pulse frequency levels.

Creating Simulated LIDAR Images of Human Poses in a Virtual Laboratory

Automated human activity recognition can provide clues about a subject’s intentions. Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio LIDAR is a partial 3D standoff sensing method that illuminates a target with rotatory or flash laser beams, analyzes the reflected lights, and provides both the distance to the target’s surface and the target’s surface shape. An array of laser reflections can be used to map the facing-side surface of a target object as a partial point cloud. Unlike a 360° surface model generated by a traditional full body scanner, the partial point cloud from a LIDAR is a viewing angle dependent 3D representation of the target shape. The resolution of these maps depends on the density of the laser detector array; a good image of a human may require hundreds of detection pixels to capture enough detail to clearly detect changes in limb positions.

Advanced Sensors for Traumatic Brain Injury (TBI)

Implanted sensors could be used to measure intracranial pressure in TBI patients. Army Medical Research and Materiel Command, Fort Detrick, Maryland The objective of this work was to use miniaturized, state-of-the-art pressure/temperature sensors engineered at Lawrence Livermore National Laboratory (LLNL) to measure the immediate increases in intracranial pressure (ICP) combined with longer-term measurements of biological ICP and intracranial temperature. The experience gathered from this work provided valuable data on sensor placement, long-term brain tissue responses to implanted sensors, and sensor capability of dual measurement of biologic ICP and impact pressure transients.
