Pixel-Scale Coated Sensors Bring Multispectral Imaging to New Users

The pixel-scale patterning of optical filters directly onto sensors has the potential to drastically simplify and scale down the cost of real-time multispectral imaging. Without moving parts, a more robust and compact system can be deployed into harsher environments than have been previously accessible for multispectral imagers.

Rugged IP-Based Video Surveillance System Keeps Taipei Trains Moving

Averaging 1.6 million passengers per day, the Taipei Metro, also known as the Taipei Mass Rapid Transit (MRT) system, is one of the busiest transportation systems in Asia and has become an important driver for business and lifestyle in Taiwan. To ensure smooth and reliable operations and keep a watchful eye on the security and safety of riders, a CCTV-based onboard video surveillance system has been in place on a number of Taipei Metro carriages since 2010. The system makes it possible for train drivers to access live video images of critical areas, and video recordings are also available for later review and analysis.

3D Machine Vision Inspection

Cognex Corporation (Natick, MA) has announced the DS1000 3D laser profiling system. The system calibrates real-world units of measurement for inspections too difficult to perform with traditional two-dimensional machine vision. The new DS1000 3D sensor reads embossed or raised characters, such as those on automobile tires; verifies the presence of low-contrast items in boxes or packages; identifies surface defects and chips; measures heights and tilts of components to determine misalignment; and calculates volumes and dimensions for food portioning. The DS1000 system is integrated with VisionPro® 3D software. VisionPro allows users to add GigE cameras for 2D inspection tasks. DS1000 is an integrated technology; a Cognex proprietary high-speed sensor and laser are both enclosed in an IP65-rated industrial housing.
