Muscle Weakness Measured with Multiphoton Imaging
ERLANGEN, Germany, Dec. 3, 2018 — Scientists at University of Erlangen-Nuremberg (FAU) have engineered an automated, high-precision biomechatronics system into a multiphoton microscope. The system allows isometric calcium ion (Ca2+)-graded force (or passive viscoelasticity measurements) and second-harmonic generation (SHG) recordings to be made simultaneously. Using this MechaMorph system, the researchers studied force and SHG in single extensor digitorum longus (EDL) muscle fibers from mice. The system accurately measured
High-Performance Computers Could Advance Application of 3D Holography
CHIBA, Japan, Nov. 30, 2018 — Researchers at Chiba University are developing a computer that can project high-quality 3D electroholography as a video — a project that they began about 25 years ago. The team, led by professor Tomoyoshi Ito, has been working to increase the speed...
Microscopy Add-On Enhances Neuronal Image Resolution Under Dim Conditions
TEL AVIV, Israel, Sept. 18, 2018 — A new add-on for laser-scanning microscopes, built from commercially available hardware and open-source software, could improve the quality of 2D and 3D imaging of neuronal activity in the living brain, even under photon-deprived imaging conditions....
Nanoscope’s 3D Superresolution Reveals Alzheimer’s Source
WEST LAFAYETTE, Ind., July 17, 2018 — A superresolution nanoscope could enable 3D imaging of amyloid plaques — a characteristic feature of Alzheimer’s disease — with up to 10 times greater detail than conventional microscopes. Researchers at Purdue University combined active shaping of...
AO-LLSM Microscope Achieves Aberration-Free Imaging
ASHBURN, Va., April 23, 2018 — Scientists have combined lattice light-sheet microscopy (LLSM) with adaptive optics (AO) to capture high-resolution 3D movies of cells deep within living systems. The AO-LLSM microscope enables cells to be viewed in their native multicellular...
Superresolution Imaging System Generates Segmented Fossil Images
PRINCETON, N.J., March 8, 2018 — Using an industrial grinder and superresolution camera, geoscientists have created 3D digital images of rock samples that can be viewed from multiple angles. Algorithms allow the computer to segment the images without human bias. Scientists used...
Microscope Provides Precise 3D Imaging of Thick Mammalian Cells
STANFORD, Calif., March 5, 2018 — A new microscope produces 3D nanoscale images of mammalian cells in their entirety. Because the axial positions of the single emitters are encoded in the shape of each single-molecule image rather than in the position or thickness of the light...
Lensless Camera Creates Detailed 3D Images Without Scanning
BERKELEY, Calif., Dec. 27, 2017 — A new camera has been developed that produces 3D images from a single 2D image without using any lenses. Called DiffuserCam, the camera consists only of a diffuser placed a few millimeters in front of an image sensor. DiffuserCam integrates concepts...
Single-Shot Approach to HSI Uses Camera Equipped With Prism
DAEJEON, South Korea, Dec. 8, 2017 — A compact, low-cost, single-shot hyperspectral imaging method has been devised, which captures images using a conventional digital single-lens reflex (DSLR) camera equipped with an ordinary refractive prism placed in front of the lens. The new,...
NIH Team Improves 3D Imaging Efficiency, Speed and Resolution
WASHINGTON, D.C., Nov. 15, 2017 — Researchers have developed a technique that improves the spatiotemporal resolution and collection efficiency of light-sheet fluorescence microscopy (LSFM), without modifying the underlying microscope. The technique instead uses reflection to improve...
Silicone Immersion Objectives Answer the Call for Higher Resolution
Sep 21, 2017 — Refractive index mismatch, and resulting spherical aberration, has historically plagued researchers interested in long-term, live-cell imaging at high resolution. The use of silicone oil objectives helps mitigate this mismatch as the refractive...
Novel STEM for 3D Imaging Improves 3D Visualization of Curvilinear Nanostructures
LAUSANNE, Switzerland, Sept. 8, 2017 — Scientists have developed a scanning transmission electron microscopy (STEM) method that generates fast and reliable 3D images of curvilinear structures from a single sample orientation. This STEM method can acquire images in a single shot, making...
A Tabletop OCT Approach Utilizes Extreme Ultraviolet Radiation
JENA, Germany, Aug. 10, 2017 — 3D noninvasive imaging with nanoscale axial resolution has been demonstrated using a high-harmonic extreme ultraviolet (XUV) radiation source. Specifically, XUV radiation was used to perform optical coherence tomography (OCT) at laboratory scale....
Sensor Market Set to Soar
Jul 28, 2017 — It is no secret that CMOS image sensor technology has undergone a rapid transformation. Driven by the consumer cellphone market’s insatiable demand for fast, high-quality images, there has been substantial investment in CMOS sensor technology,...
Handheld Optoacoustics Device Sees Under Skin
MUNICH, July 10, 2017 — A handheld scanner for analyzing the skin of psoriasis patients was shown to provide clinically relevant information, such as the structure of skin layers and blood vessels, without the need for contrast agents or radiation exposure. The device...
Images Alone Form a Dynamic 3D City Model Using Machine Learning
ZURICH, May 22, 2017 — “VarCity,” a technology platform that can be used to create 3D city models using image data alone, can use, evaluate and automatically combine images from all types of sources, including aerial photography, panoramic images taken with...
Holographic Process Uses WiFi to Generate 3D Images
MUNICH, May 16, 2017 — A holographic imaging process that generates 3D images using the microwave radiation of a Wi-Fi transmitter could be used in automated industrial facilities to track objects as they moved through production. Although processes already exist that...
Optical Diffusers Improve Definition, Viewing Angle for 3D Holograms
DAEJEON, South Korea, Feb. 17, 2017 — A wavefront shaping technique has been used to create a dynamic 3D holographic image with a viewing angle of 35 degrees in a volume of 2 cm in length, width and height. Use of the technique was shown to yield a 3D holographic display that performed...
Asia-Pacific Eyes Photonics Market Growth
Feb 13, 2017 — The global photonics market will continue its fervent growth in the coming years, according to a number of reports, as technology advances industrywide. Progressing the most is the telecommunications sector, which is expected to become the largest...
Community Colleges: Preparing the Future Photonics Workforce
Aug 5, 2016 — World-renowned astronomer Carl Sagan once said, “Somewhere, something incredible is waiting to be known.” Community college photonics and optics programs are preparing students to find it. About 30 community colleges around the U.S....
