Laser Ophthalmoscope: A Handheld Tool for Rural Optometry
Adaptive optics is a technology to compensate for distortions in an imaging system. It typically uses a deformable mirror, that deforms to adjust for incoming distortion as the image is taken. It has been ...
Optical Frequency Combs for Molecular Fingerprinting
Researchers at the University of Colorado, Boulder have been experimenting with laser sources called optical frequency combs to find a new way of studying molecular structures. Frequency combs get their ...
Machine Learning Enables OCT Imaging of Optic Nerve Head
Medical imaging of the optic nerve head (ONH) is immensely important to study vision disorders like nearsightedness and glaucoma. Doctors traditionally use optical coherence tomography (OCT scans) to ...
Light Injection in Waveguide Connected Microdisks (WCM)
Researchers from the Harbin Institute of Technology at Shenzhen and Shanxi University have created a new configuration for waveguide connected microdisks (WCM). Their method could significantly reduce ...
Deformable Mirror Fights Thermal Distortion in Q-Switched Lasers
Researchers at Tsinghua University look to optimize the performance of passively Q-switched lasers by confronting effects of thermal distortion. Their solution, a customized deformable mirror, proves to be ...
How Does Optical Storage Work
Within the past few decades the ability to optimize information storage has become increasingly important. The use of data to guide decision-making continues to grow rapidly, while the amount of data is ...
Laser Speckle Strain Imaging: A New Method to Study Delayed Fractures
A team of researchers from the Wageningen University in the Netherlands has devised a new method of imaging solids as stress is applied to them. This method, called laser speckle strain imaging, reveals ...
BRAD-OCT for Characterizing Brain Diseases
Researchers at the Medical University of Vienna and TU Wien look to optimize optical neuroimaging with their innovative BRAD-OCT technique. Their method, published in the June edition of Biomedical Optics ...
Non-Ablative Fractional Lasers Fighting Colorectal Cancer
A group of South Korean researchers recently published research revealing a new and innovative way to treat colorectal cancer and precancerous tissues using non-ablative fractional lasers (NAFLs). This new ...
Confocal Microscope on Smartphones: Skin Disease Diagnosis
Researchers from around the world came together to develop a low-cost smartphone confocal microscope for imaging human skin in vivo. The team’s main concern: disease diagnosis in low- and middle-income ...
