2 MP HDTV Format Cameras

Camera manufacturer Basler (Ahrensburg, Germany) has expanded its ace camera family to include monochrome and color models in full HD format. The acA1920-25 cameras deliver speeds of 25 fps at 2 MP resolution (1920 pixels x 1080 pixels). They come with a Gigabit Ethernet or USB 3.0 interface and are 100% compliant with GigE Vision and USB3 Vision.

Image Processing Software

The EyeVision image processing software by EVT (Karlsruhe, Germany) now also supports the liquid lens by Opto-Tune. With the new driving module this is easier than ever because even in the case of different component heights, the focus can be adjusted automatically and fast with the EyeVision software.

Multi-layer Thickness Measurement System

Saelig Company, Inc. (Fairport, NY) has announced the OptiGauge MLS™, a patented non-contact thickness measurement system that is non-destructive and since it is self-calibrating, it leaves no opportunity for operator error. The OptiGauge MLS™ can measure each translucent coating in an object up to 20 layers thick - the thickness of individual layers and total overall thickness is calculated automatically.

New Rotary Sensor Keeps Conveyor Belts Running Smoothly

Rotary sensors can help determine the position of a moveable body in relation to an axis. They are essential to the smooth running of car engines in the automotive industry, for example. In factories, goods and products are transported from one processing station to the next via conveyor belt. For the transfer from one belt to the next to run smoothly, it must take place precisely at a specific position, which means knowing the relative position of objects on the conveyor belts as they move towards each other. This can be determined from the angle of rotation, which refers to the position of a moveable body to an axis.

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.

OCULLAR Provides Around-the-Clock Ocean Measurements

A team led at NASA's Goddard Space Flight Center in Greenbelt, Md., has developed an instrument capable of observing ocean color during normal sunlight conditions and under moonlight — a first-ever capability that will allow scientists to monitor the health and chemistry of the planet’s oceans literally around the clock.The prototype Ocean Color Underwater Low Light Advanced Radiometer (OCULLAR) has shown in field testing that it can measure ocean color under low-light conditions across multiple wavelength bands, from the ultraviolet to the near-infrared. In contrast, current remote-sensing instruments can obtain measurements — based on electromagnetic energy emitted by the sun, transmitted through the atmosphere, reflected off Earth’s surface, or upwelled from water masses — only during daylight hours, said Principal Investigator Stan Hooker.Of particular interest to scientists studying ocean color is phytoplankton, the microscopic ocean plants that form the base of the oceanic food web. The tiny plants use sunlight and carbon dioxide to produce organic carbon. This process, called photosynthesis, is possible because plants contain chlorophyll, green-colored compounds that trap the energy from sunlight. Because different types of phytoplankton contain different kinds of chlorophyll, measuring the color of a particular area allows scientists to estimate the amount and general type of phytoplankton there. Since phytoplankton also depend on specific conditions for growth, they frequently become the first to be affected by pollution or some other change in their environment.Until now, however, obtaining these measurements was limited to daylight hours and only during the spring, summer and fall months in the polar regions — a problem Hooker sought to correct with OCULLAR. The successful OCULLAR demonstration leads the way to anticipated commercialization and creates a new capability for oceanographers, climate scientists, and others interested in quantifying, understanding, and monitoring the biological productivity of oceans, coastal areas, and inland waters.SourceAlso: Learn about a Data Assimilation System for Coastal Ocean Prediction.
