AEGIS Imaging Software Unearths Mars Rocks

In mid-October, a NASA-developed software called AEGIS was uploaded to the Mars Science Laboratory (MSL) rover. The AEGIS technology, winner of NASA’s 2011 Software of the Year award, will soon allow scientists on the ground to more easily identify interesting rocks and other terrain features on the Red Planet.

Hybrid Technology Advances Laser Material Processing

MultiWave Hybrid Technology* combines multiple laser beams with various wavelengths into a single coaxial laser beam. There are existing systems using two different laser wavelengths independently, but this is the first technology capable of combining multiple wavelengths into a single beam, providing a valuable tool for the development of novel material processing technologies.

SPIE Photonics West 2016 Preview

The SPIE Photonics West 2016 technical conference and exhibition returns to The Moscone Center in San Francisco, February 13-18, offering attendees the opportunity to explore the latest innovations in lasers, photonics, optics, optoelectronics, biophotonics, biomedical optics, 3D printing and more. As in the past, the event will once again kick off with BiOS, the world’s largest biomedical optics conference, before transitioning into the Photonics West conference and exhibition. Last year’s event hosted more than 21,000 attendees and put the products and services of over 1,250 exhibitors on display. More than 4,800 technical papers will be available to conference participants throughout the week.

Using Radiation-Hardened Optoelectronic Devices

Optoelectronic components must be protected from the radiation they are exposed to in military, space and nuclear environments to prevent malfunction and damage. Radiation hardening electronics makes them resistant to this damage by letting them retain characteristics, and keeps imaging and electrical performance consistent with pre-radiation values. This is especially critical for components used in applications like a satellite or a nuclear reactor that cannot be accessed and must work properly for many years.

How Quantum Dots and Ultra HD Are Changing the Way TV Displays Are Made

Chances are you’re familiar with HDTV. Most of us have one of these in our living rooms. In fact, according to a recent study, more than 80% of US residents probably have at least one HDTV in their homes. And there’s a good possibility these sets are LCDs. They may be a few years old but they’re thin, look great hanging on the wall and basically do their job well. Some of these HDTVs also have 3D capabilities but the required glasses have long been lost to the couch cushions or the dog ate them or they just never made it out of the packaging due to lack of content support by broadcasters.

Using a Wide-Band Tunable Laser for Optical Filter Measurements

The concept of dense wavelength division multiplexing (DWDM) in fiber optic communication networks gained traction when optical amplifiers became available. Able to amplify an entire wavelength grid at once, they removed the need to first demultiplex, then convert every channel to an electrical signal, regenerate it, convert it back to an optical signal, and finally multiplex all channels onto a single optical fiber.

3D Machine Vision Using Laser Triangulation

Applications for 3D machine vision are rapidly expanding in a variety of industries for several reasons. The first is that vision systems can lower production costs by increasing yields and/or reducing scrap product and wasted raw material. One example of this would be extruded products from various materials (rubber, plastic, metal), where it’s vital to know as soon as the process goes out of specification.
