A powerful materials discovery platform created at Harvard University to dramatically accelerate the process of screening millions of molecules for use in future technologies will now speed the commercial development of next-generation electronic displays.
Nine engineering-led interdisciplinary teams of researchers from 17 institutions across the United States are attempting to defy the laws of classical physics with potentially groundbreaking optical and acoustic studies funded by the National Science Foundation (NSF).
Developers of imaging systems have long been beholden to certain rules of optics designs so well established and seemingly immutable as to be treated as virtual “laws” of physics.
For all the promise they have shown in the lab, polymer solar cells still need to “get on a roll” like the ones employed in printing newspapers so that large sheets of acceptably efficient photovoltaic devices can be manufactured continuously and economically.
Nothing wakes you up like a good “cup o’ Jo”! Or maybe an ice cold glass of water? Compare the difference between the two with high speed infrared imaging from the X6900sc.
Nothing could beat the feeling of shooting a watermelon and tannerite with an AR15.
Champagne anyone? Prolong the party with this video using the high speed infrared capabilities of the X6900sc.
A water balloon plus a sharp object equals a splash of a visual effect! Take it all in with the high speed infrared capabilities of the X6900sc.
If you need to stop motion on fast-moving targets or targets that heat and cool rapidly, FLIR’s high speed thermal cameras offer the fast frame rates and integration you need. FLIR’s newest camera, the X6900sc, can record 1000 fps of high speed data at full 640 x 512 resolution – meaning researchers can perform dynamic analysis of jet engine turbine blades, supersonic projectiles, explosions, and more, without losing areas of the frame to windowing.
The new Phantom® VEO family of cameras from Vision Research is made up of four high speed cameras designed to provide information on high speed events within scientific and industrial applications. The VEO710 and VEO410 models feature frame rates exceeding 7,000 fps, making these models ideal for traditional high-speed motion analysis. The four-megapixel VEO640 and VEO340 are optimized for scientific imaging applications where higher resolutions are important.

Continuing advances in high-resolution sensors with higher pixel densities and smaller pixels are challenging optics manufacturers to produce lenses of increased performance. To understand how lenses can affect the performance of imaging systems, it is necessary to grasp the physics behind diffraction, lens aperture, focal length, and the wavelength of light (see “Matching Lenses and Sensors,” Vision Systems Design, March 2009). Additionally, other design limitations also restrict the optical capabilities of a lens, even before manufacturing tolerances are taken into account.
It is often necessary to have an understanding of how to chop a laser beam. Chopping diode lasers electrically is actually less costly and much simpler than doing so mechanically. This white paper walks through the process of chopping a diode laser beam at high speeds and low noise.
Tissue autofluorescence spectroscopy, or the measurement of intrinsic light emissions from biological agents upon excitation, is utilized in a variety of biomedical research for differentiating between diseased and normal tissues. Researchers interested in the correlation between temperature and tissue autofluorescence spectroscopy during surgery are finding their answers with the help of thermal imaging. FLIR offers a scientific camera with the ideal resolution and lens magnification for such research. This application note offers the full story on how researchers used FLIR cameras and ResearchIR software to work to gain a greater understanding of this surgical tool.
Thermal Imaging has been around for nearly a quarter of a century, and has grown considerably in the capability of providing scientists with heat radiation images that would normally be invisible to the naked eye. Thermal imaging is simply made up of a thermal scene, a lens, a sensor, and a display. But how do you focus heat? What kind of sensor detects heat, and how do you display it? This article offers a short Infrared 101 overview, and covers fundamental terms and concepts of thermal imaging.
Physicists have devised a new method to create a quantum network of atomic clocks consisting of ensembles of hundreds of entangled atoms. This network, they claim, is significantly more stable and accurate than existing atomic clocks, and has several critical applications, including the detection of gravitational waves.
A novel way to detect and harvest low-energy photons using heterostructures made of 2D materials and graphene may overcome the limitations of conventional semiconductor devices, and could lead to greater speed and efficiency in optoelectronic applications.
