An international team of researchers has used an unconventional imaging technique known as ghost imaging to make spectroscopic measurements of a gas molecule. The new approach by scientists at Tampere University of Technology ...
Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. The inexpensive and compact sensors could offer an alternative to the magnetic ...
A new way of rapidly identifying bacteria, which requires a slight modification to a simple microscope, may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help ...
The basic quanta of light (photon) and sound (phonon) are bosonic particles that largely obey similar rules and are in general very good analogs of one another. Physicists have explored this analogy in recent experimental ...
Scientists from ITMO University developed a laser for precise measurement of the distance between the moon and Earth. The short pulse duration and high power of this laser help to reduce errors in determining the distance ...
From almost instantaneous wireless transfer of huge amounts of data and easy detection of explosives, weapons, or harmful gases, to safe 3-D medical imaging and new advances in spectroscopy —technologies based on terahertz ...
A team at the University of Warsaw, Faculty of Physics has created a laser capable of generating ultrashort pulses of light even under extremely difficult external conditions. This unique combination of precision and resilience ...
A new type of pressure sensor based on light could allow the creation of sensitive artificial skins to give robots a better sense of touch, wearable blood-pressure monitors for humans and optically transparent touch screens ...
A compact 'on-silicon-chip' laser has been developed by A*STAR researchers that boasts both excellent confinement of light for lasing and the ability to efficiently share the laser light with nearby components.
As the world's exponentially growing demand for digital data slows the Internet and cell phone communication, City College of New York researchers may have just figured out a new way to increase its speed.
