Holography technology can restore the complete light field information of the recorded object, which has important applications in fields like biological microscopic imaging and optical micromanipulation. One important frontier in holography is the reconstruction of realistic 3D scenes. However, the development and application of holographic technology have been hindered by the huge amount of data of the 3D scenes and the laser coherence, which leads to the slow capturing speed of the real 3D scenes and the serious speckle noise of the holographic reproduced image.

A team of researchers has collaborated to develop a holographic camera based on liquid lens technology, capable of recording high-quality holograms of real 3D scenes in a...]]>

$20M Grant Funds Portable Eye Scanning Tech
The Advanced Research Projects Agency for Health (ARPA-H) has awarded $20 million to Chao Zhou, a professor of biomedical engineering in the McKelvey School of Engineering at Washington University in St. Louis, to support the development of a portable OCT system. The solution could offer advanced eye screenings to many more patients at lower costs. Additionally, the technology could be used in additional applications, including cardiology, dermatology, dentistry, endoscopy, and urology.

Zhou plans to build the portable system using a design based on PICs and custom-designed electronic integrated circuits (ICs). This, he said, will simplify the assembly process and lower production costs, making OCT more accessible to a wider range of...]]>

Lidar Methods Combine for Nonmechanical, Compact Solution
In a newly developed lidar system, researchers at Kyoto University integrated 3D flash and beam-scanning laser light sources to create a 3D, nonmechanical lidar system. The system can measure the distance of poorly reflective objects in the field of view (FOV) and automatically track the motion of these objects — a capability not found in conventional lidar and one that will enable autonomous vehicles to drive more safely, the researchers said.

Most lidar systems rely on moving parts such as motors to scan the laser beam, making them bulky, expensive, and unreliable. Flash lidar, a nonmechanical lidar system that simultaneously illuminates and evaluates the distances of objects in the FOV with a single beam, cannot measure the...]]>

NASA Reveals First Exoplanet Images Taken by Webb Telescope
Astronomers from the University of Exeter in the U.K. used NASA’s James Webb Space Telescope to capture the first direct image of a planet outside our solar system. The image, shown through four different light filters, demonstrates how the telescope’s infrared capabilities can lead the way to observations that will reveal more information than previously possible about exoplanets.

“This is a transformative moment, not only for Webb but also for astronomy generally,” said Sasha Hinkley, associate professor of physics and astronomy at the university, who led the observations with a large international collaboration. Webb is an international mission led by NASA in collaboration with its partners, the European...]]>

QLM Gains $14.5M in Financing, Launches Collaboration with Schlumberger
Lidar imaging company QLM Technology closed a £12 million ($14.5 million) series A financing round and signed a collaboration agreement with Schlumberger, an oilfield services company. QLM’s lidar camera is able to monitor, detect, locate, and quantify greenhouse gas emissions. A related version of the product enables remote quantification. The technology is inherently scalable due to low-cost manufacturing at high volume.

Ambarella Launches Collaborations in Software, Advanced Sensing
Ambarella Inc., an edge AI semiconductor and software company, and Helm.ai, a developer of next-generation AI software, have released a perception software for the Ambarella CVflow AI SoC architecture to enable Helm.ai’s ADAS system software on the Ambarella platform. The development allows the companies to iterate on technical approaches to the developing needs of the automotive industry.

Helm.ai and Ambarella demonstrated the initial integration of Helm.ai technology at CES 2020. At this year’s event, the companies demonstrated an integration of the Helm.ai full 360° surround-view camera perception stack for L2+/L3 and autonomous driving on Ambarella’s automotive grade CV2FS SoCs. This integration leverages...]]>

Metasurface Tech Enables Polarization Imaging on Almost Any Camera
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a metasurface attachment that can turn almost any camera or imaging system, even off-the-shelf systems, into polarization cameras.

The technology developed in the Capasso Lab at Harvard could, in theory, establish a mechanism to turn a standard camera into a polarization camera, albeit without the capacity to identify material compositions.

The attachment uses a metasurface of subwavelength nanopillars to direct light based on its polarization and compiles an image that captures polarization at every pixel. As with previously developed metasurface technology, the optical devices can be manufactured using existing...]]>

Lensless Camera Captures Cellular-Level Details in 3D
Rice University researchers have tested a tiny lensless microscope called Bio-FlatScope, capable of producing high levels of detail in living samples. The team imaged plants, hydra, and, to a limited extent, a human.

A previous iteration of the technology, FlatCam, was a lensless device that channeled light through a mask and directly onto a camera sensor, aimed primarily outward at the world at large. The raw images looked like static, but a custom algorithm translated the raw data into focused images.

The device described in current research looks inward to image micron-scale targets such as cells and blood vessels inside the body, and even through skin. The technology combines a sophisticated phase mask to generate patterns...]]>
