Hologram Recording Medium (US 7385740)

From the very first use of lasers, a key safety practice has involved providing some type of indication to alert people that they are about to enter a room where a laser is on or powered up. Further...

There is more to a bank note than the numerical figures that appear on it. The elements that go unseen by most are just as important as the clearly visible information on the currency. The U.S....

Lockheed Martin-owned company Lockheed Martin Aculight Corp. has secured a $220.8 million contract from the U.S. Army to develop, integrate, manufacture, test, and deliver high-energy laser systems...

The capability to detect and track small, moving objects remotely, in all conditions, is crucial to many surveillance and monitoring missions. It is also an ongoing challenge. According to Tian...

Surface-Mount Silicon and Indium Gallium Arsenide Photodetectors from Advanced Photonix are designed for high-speed response applications. The surface-mount devices are assembled in compact,...

The LSP-LRS-1200 and -1000 from LumiSpot Tech are 905-nm laser ranging modules that can be used in laser range finding, distance sensing, consumer, and defense applications. The LSP-LRS-1200 can...

The Mali-C55 image signal processor from Arm Ltd. is a compact device for Internet of Things and embedded market vision systems. With multicamera capability for up to eight separate inputs,...

Imaging has long been used in industrial processes to measure, monitor, control, or otherwise manage the production of goods. The challenge to the process designer is to develop a tool that captures...

To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...

Hyperspectral imaging spectroscopy has developed dramatically from a large, complex, remote-sensing satellite- or aircraft-based system into a rugged, compact, economically priced imaging and...

Image intensification, the basis of night vision, is a complex conversion of energy particles that occurs within a vacuum tube. An image-intensifier system works by collecting photons through an...

OPTOMAN offers high LIDT, environmentally stable laser optics featuring excellent spectral performance.

Metasurfaces based on subwavelength patterning have major potential for realizing arbitrary control of the wavefront of diffracted light by achieving local control of the phase amplitude and...

In this webinar, Björn Kemper, Ph.D., will introduce quantitative phase imaging (QPI) and digital holographic microscopy (DHM), providing examples and an overview of representative applications...

Head-up displays (HUDs) and augmented reality (AR) pose unique optical design challenges that are not yet resolved. Both types of systems impose tight constraints in size and weight, while requesting...

Information from the universe can be more than just a two-dimensional snapshot. These digital assets can be transformed to enable us to listen to, feel, or virtually move through cosmic objects....

The recording of three or more separate holograms having a different color on a medium, so that illumination with a tricolor beam yields three separate wavefronts, each representing one of the...

A computer-generated hologram (CGH) is a holographic image produced using computational methods and algorithms, rather than traditional optical techniques. CGHs are generated entirely in digital form...

Multiple exposures of holograms, one for each position of a vibrating image, that are used for vibration analysis and that yield a record of the time-averaged irradiance distribution at the hologram...

Lensless microscopy, also known as computational or holographic microscopy, is an imaging technique that captures and reconstructs microscopic images without the use of traditional lenses. Instead of...
