Dual-Field-of-View Multiband Optics
Multi-spectral-band systems are steadily emerging as a desired feature in a camera system. Each spectral band offers different image characteristics. Shorter-wavelength spectral bands provide the potential for better resolution due to the smaller impact of diffraction on the size of the optics blur. This means...

Color-Changing Surface Tunable Through Electrical Voltage
Video screens are made up of hundreds of thousands of pixels that display different colors to form the images. With current technology, each of these pixels contains three subpixels — one red, one green, and one blue. A new method was developed to tune the color of the subpixels. The new...

Whether it is the industrial smart robot in the age of the Industrial Internet of Things (IIoT), using three-dimensional data to orient itself in its working space, the reverse vending machine counting empty bottles in...
Briefs: Imaging
Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can't be seen by the...
INSIDER: Sensors/Data Acquisition
A growing safety concern for pilots and aircraft passengers is laser strikes, or the aiming of high-power laser pointers at aircraft. To address the present lack of effective laser...
Briefs: Materials
Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity —...

Two basic components make up the value added to a work piece by the micro-electric discharge machining (μEDM) process: form and surface finish....
Articles: Photonics/Optics
Four lasers can be used for micro welding: pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG), continuous wave (CW) fiber, quasi continuous wave (QCW) fiber, and nanosecond fiber. Each laser type...
News: Imaging
For years many engineers have assumed that you cannot encode more than one holographic image in a single surface — at least without losing resolution. Caltech researchers made the idea a reality.
