OSIRIS-REx Launches
On Sept. 8, 2016, OSIRIS-REx lifted off from Cape Canaveral, Florida on a ULA Atlas V rocket to begin its seven-year mission to sample an asteroid. The Applied Optics Lab (AOL) designed three cameras in OSIRIS-REx.

Lens-design Software: Freeform LED lens-design approach produces high uniformity
One of the most actively developed uses for freeform optics right now is as light collectors and uniformizers for spotlight and directional-floodlight general-illumination LEDs. Due to a diffuse—and often nonrotationally symmetric—directional light output, a bare white-light LED device itself (usually consisting of a flat blue LED with a layer of yellow YAG phosphor), while very bright, cannot efficiently serve as a floodlight illuminator; it needs to be paired with optics. Freeform optics, with their many tweakable degrees of freedom, are an ideal choice.
Nature’s designs inspire research into new light-based technologies
Solutions required for progress on the frontiers of photonics technology are close at hand: in nature, when viewed through the perspective of engineer, says Montana State University optics researcher Joseph Shaw. Along with Rongguang Liang of the University of Arizona, Shaw chaired the ‘Light in Nature’ conference presenting new research in the field last month at SPIE Optics + Photonics and being published in the SPIE Digital Library.
Soon goggle to help surgeons locate tumours in real time
There could soon be cheaper and more lightweight tools, such as goggles or hand-held devices, to identify tumours in real time in operating rooms as researchers have developed a dual-mode imaging technology, an improvement over single mode imaging.
Dual-mode imager could aid cancer surgery
Surgical goggles could combine near-IR fluorescence and visible reflectance signals to ensure complete tumor removal.
Soon goggle to help surgeons locate tumours in real time
American researchers developed a new technique that could help surgeons identify tumors in the body through a reasonable and more efficient process.
