A new light-based technique could essentially control memories, showing potential for treating brain-related conditions such as Alzheimer’s disease. A team from the University of California, San Diego, has discovered how to use optogenetics to deactivate and then reactivate memories in the brains of genetically engineered rats. This is the first evidence demonstrating that this can be done by stimulating nerves in the brain via synapsis. “We can form a memory, erase that memory, and we can reactivate it at will by applying a stimulus that selectively strengthens or...Read full articleRelated content from Photonics MediaARTICLESNIR Spectroscopy Could Provide Window into AD Pathology, TherapeuticsTo detect Alzheimer’s disease (AD) in its early stages, researchers at the VA Bedford and VA Boston Healthcare systems developed a noninvasive optical technique that uses near-infrared...Photonics.com 9/1/2021Optogenetic Tools Use Blue Light to Restore Cell FunctionResearchers from the University of Cincinnati (UC), the University of Illinois Urbana-Champaign (UI), and the University at Buffalo (UB) used an optogenetic technique to bring together mitochondria...BioPhotonics Nov/Dec 2022 IssueTechnique Enables In Vivo Vascular Imaging at Single-Cell ResolutionA two-photon fluorescence imaging method developed by researchers at the University of Hong Kong and the University of California, Berkeley was able to image the flow of individual blood cells at...BioPhotonics Nov/Dec 2022 IssueDiamond Defects Boost Magnetic Field Sensing for Brain Activity MappingA team from Fraunhofer Institute for Applied Solid State Physics (Fraunhofer IAF), with diamond sensing technology experts from RMIT University, demonstrated that magnetic-field-dependent emission...Photonics.com 7/12/2022PRODUCTSOpen-aperture Voice Coil Linear MotorThe HVCM-025-038-003-02 open-aperture voice coil linear motor from Moticont is a 1-in. body diameter servo device.

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 HandbookUnderstanding Surface Quality: A Practical Guide: Surface quality is one of the most scrutinized specifications in the optics industry. It is critical that the suppliers and customers have a consistent approach during the inspection process. These guidelines are intended to help ease communication between suppliers and customers for better products and business.Surface quality has become one of the most poorly understood specifications in the optics industry. A significant portion of the confusion stems from the two major competing (and largely...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery, and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms).
