A group of Italian researchers has developed a modification to optical mammography instrumentation that increases the sensitivity of the medical imaging technique by up to a thousand-fold. The researchers will report the advancement at the OSA Biophotonics Congress ‘Biomedical Optics’...

Smartphone technology based on the usage of simultaneous localization and mapping (SLAM) and augmented reality (AR). This technology enables medical personnel to reconstruct 3D body sections quickly, only by holding the smartphone around the area of interest. ...

A multilayer pair of materials, tungsten carbide and silicon carbide, was used to prepare high-efficiency, high-numerical aperture (NA) multilayer Laue lenses (MLLs). In a series of studies, Saša Bajt of Deutsches Elektronen-Synchroton (DESY) and co-workers used a pair of MLLs to achieve...

A new method to make a low-cost, high-quality lens quickly using a 3D printer has promising potential to create optical imaging lenses, customized contact lenses for correcting distorted vision, or to even turn iPhones into microscopes for disease diagnosis....

The EU project called Laser and Ultrasound Co-analyzer for Thyroid Nodules (LUCA) aims to develop a new, noninvasive low-cost device that will provide more specific results in thyroid nodule screening and enable better diagnosis of thyroid cancer. ...

The research team's method provides much faster diagnosis as basis for selecting reliable therapy. Neugebauer, who works at Leibniz-IPHT and University Hospital Jena, points to tiny electrodes that are fixed on the surface of a stamp-sized chip, which secure bacteria...

Scientists have demonstrated that a three phase-grating moiré neutron interferometer in a neutron beam could be a robust candidate for large area interferometry applications and for the characterization of materials. The technique would provide neutron interferometry tools with the ability...

A novel quantum effect observed in a carbon nanotube film could lead to the development of near-infrared lasers and other optoelectronic devices, according to scientists....

Researchers have developed a flat optical component that is simultaneously a metalens, a microscope objective that can resolve details smaller than a wavelength of light, and an optical vortex and hologram generator. Each functionality is controlled by a different wavelength...

Recent years have seen an explosion of research in flat optical components fashioned with so-called metasurfaces – intricately engineered, planar configurations of subwavelength elements. But most of these flat optical elements have lacked a means of active control, a drawback...
