Space-Based Hyperspectral Imaging

As space-based digital camera imagery is evolving, more and more advanced imaging technologies are being deployed in space to see more of the “unseen.”

X-Ray Crack Detectability

The models allow users to optimize X-ray radiography setups, for the detection of crack and crack-like flaws, to penetrate various materials to show internal structures of parts.

Miniature Optical Fiber Treatment Device Offers More Effective Cancer Immunotherapy

Cancer immunotherapy, one of the most important and promising therapies for cancer treatments, is being used by oncologists to treat patients suffering from many different cancers including breast, cervical, colon, stomach, and skin.

New Imaging Technology Reduces Need for Skin Biopsies

Instead of surgically removing a sample of skin, sending it to a lab, and waiting several days for results, your dermatologist takes pictures of a suspicious-looking lesion and quickly produces a detailed, microscopic image of the skin. This could become routine in clinics.

Making Measurements with a Fine-Toothed Comb

Enter the frequency comb, a Nobel Prize-winning device and the result of decades of research from NIST and others. The comb generates a billion pulses of light per second, which bounce back and forth inside an optical cavity.

Let’s Get Small: New Argonne Method Greatly Improves X-Ray Nanotomography Resolution

A group of scientists led by the U.S. Department of Energy’s Argonne National Laboratory has created a new method for improving the resolution of hard X-ray nanotomography.

Pulsed 2-Micron Laser Transmitter

The design produces a compact, efficient, long-lifetime laser transmitter as needed for use in space, while also having potential applications as an airborne or ground-based wind measurement tool.

Optical Strain for Precision Measurements and Certification

Optical strain is material independent and measures the response of the integrated system, so designers can get a measure of the true response and strength of their designs.

It achieves 40 channels by combining a frequency comb light source based on a new photonic crystal resonator developed by the National Institute of Standards and Technology (NIST) with an optimized mode-division multiplexer.

Upside-Down Design Expands Wide-Spectrum Super-Camera Abilities

Plasmonics is a technology that essentially traps the energy of light in groups of electrons oscillating together on a metal surface.

Rice ‘Metalens’ Could Disrupt Vacuum UV Market

Tests showed the metalens they made could focus its 197-nanometer output onto a spot measuring 1.7 microns in diameter, increasing the power density of the light output by 21 times.

New Technology Could Make Biopsies a Thing of the Past

MediSCAPE is a highspeed 3D microscope capable of capturing images of tissue structures that could guide surgeons to navigate tumors and their boundaries without needing to remove tissues and wait for pathology results.

Designing a Human-Robot Collaboration System

Scientists analyzed the stability of the collaborative system based on speed and accuracy, as well as the conditions required for successfully performing tasks from geometric, force, and posture viewpoints.

Challenges of Fabricating and Coating Laser Crystals

Because laser crystals are sensitive optical components and are often used with high-power lasers, depositing the correct coatings onto them without introducing any defects is essential.

Time-of-Flight: Highly Reliable 3D Imaging for Challenging Applications

There are multiple technologies based on the ToF concept. Generally, all of them are synchronized with a light source and estimate the distance by calculating the time taken for the light to travel from the camera to the object and then back again.

Meta Optical Elements

The size and complexity of lens systems can be reduced through flat optics that are based on pioneering meta optical elements (MOEs).
