High Dynamic Range Imaging (HDRI) Upgrades Inspection Results

HDRI features capture details when the environment, or the objects themselves, are both bright and dark. Designers and operators of automated inspection systems have long been challenged with completing accurate inspections when those tasks required high dynamic range, or when there was a need to capture critical details in objects or environments with high contrast between their brightest and darkest areas.

Advanced Holography Offers 3D Fire Measurements

In a propellant fire, large molten aluminum drops form at the burning surface. The drops are lofted into the environment and can severely damage anything that they fall on. Liquid breakup must be understood to predict the scale and intensity of such fires.

Cameras Provide Critical Data for NASA Rocket’s First Flight

On March 11, NASA tested the powerful five-segment booster for NASA’s new rocket, the Space Launch System. To provide critical data for the rocket’s first flight, eight cameras with more than 40 different settings — including varying exposures — were set up near the forward portion of the booster. During the two-minute test, the cameras were computer-controlled and cycled through pre-programmed settings.

New Method Generates High-Resolution, Moving Holograms in 3D

The 3D effect produced by stereoscopic glasses used to watch movies cannot provide perfect depth cues. Furthermore, it is not possible to move one’s head and observe that objects appear different from different angles — a real-life effect known as motion parallax. Researchers have developed a new way of generating high-resolution, full-color, 3D videos that uses holographic technology. Holograms are considered to be truly 3D, because they allow the viewer to see different perspectives of a reconstructed 3D object from different angles and locations. Holograms are created using lasers, which can produce the complex light interference patterns, including spatial data, required to re-create a complete 3D object. To enhance the resolution of holographic videos, researchers used an array of spatial light modulators (SLMs). SLMs are used to display hologram pixels and create 3D objects by light diffraction. Each SLM can display up to 1.89 billion hologram pixels every second. Source:

CMOS Smart Camera

VC F series intelligent cameras from Vision Components (Ettlingen, Germany) provide a 4 x 1 GHz computing power. Equipped with a programmable GPU, the systems use the VC Linux operating system. The cameras feature either one or two remote 1/1.8" CMOS sensors connected by a 30 mm or 80 mm cable; the two-sensor version is also suited for stereo camera applications. Depending on the model, the sensors provide a 1,280 × 1,024 (WVGA) or 1,600 × 1,200 pixel resolution. A 1 GBit Ethernet interface enables integration into automation environments. The VC F series includes two USB interfaces and an HDMI output.
