CAMBRIDGE, Mass., July 17, 2014 — A small, autonomous helicopter can direct lighting just where a photographer needs it. Researchers at MIT and Cornell University developed the drone system to respond to the movements of a photographer and her subject using lidar and input from the photographer’s camera. They tested...Read full articleRelated content from Photonics MediaARTICLESParticle Cavity Cooling Could Aid Quantum Effects StudyA new method for cooling levitated nanoparticles using optical tweezers, discovered by researchers at the University of Vienna, the Austrian Academy of Sciences, and the Massachusetts Institute of...EuroPhotonics Summer 2019 IssueSTORM Pioneer Wins One of Six $3M Breakthrough PrizesThe Breakthrough Prize Foundation and its sponsors — Sergey Brin, Priscilla Chan and Mark Zuckerberg, Ma Huateng, Yuri and Julia Milner, and Anne Wojcicki — announced the recipients of...BioPhotonics January 2019 IssueShining Light Through Bleach Creates Fluorescent Quantum DefectsUsing household bleach and light, MIT researchers have created fluorescent quantum defects in carbon nanotubes.

Digital ultraviolet imaging is becoming increasingly affordable and lends itself to a number of interesting applications that have been largely overlooked, and digital sensors are available that span the UV spectrum from 200 to 400 nm.Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookVibration Control: Limiting Mechanical Noise: Vibration control plays a critical role in research and industry. Mechanical noise, for example, can obscure high-resolution images and affect the quality of nanotechnology processes. Fortunately, vibration can be controlled through proper experimentation, process design, and the use of specialized equipment.In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...Photonics HandbookWHITEPAPERSUsing Lighting To Optimize Camera PerformanceA rule of thumb in imaging is that there can never be too much light.
