Photodiodes: Detecting Photons with Electrons
Photoelectronic devices combine the vast use of electronics for processing information with the detection and the manipulation of light. Devices such as photodiodes are useful for detecting incoming light ...
Laser Doppler Flowmetry: Measuring Blood Flow with Light
In 1842, Johann Doppler delivered his paper on Doppler effect to Royal Bohemian Society. In his paper “On the Colored Light of Double Stars and Some Other Heavenly Bodies”, he arrived at the ...
Optical Myography: Detecting Hand Posture by Looking at Forearm
Optical myography is a technique that visually inspects the human forearm to determine the hand posture. Hand posture is a communication element as important as the language itself. Human hand gesture ...
Optical Vehicle to Vehicle Communication System: How It Works
Vehicle-to-vehicle (V2V) communication system enables vehicles to wirelessly exchange information about their speed, location, and traffic information. The technology behind V2V communication allows ...
Shape Reconstruction Methods in Continuum Robot
In recent medical research fields, continuum robot is becoming a prevalent topic because it can traverse confined spaces and manipulate objects in complex environments due to its compliant structure. With ...
Visual SLAM: Sensor Application in Autonomous Mobile Robots
Visual SLAM is now a trending approach in autonomous mobile robot development. Mobile robot is the one capable of transporting itself from place to place. For example, the first mobile robot emerged as a ...
Optimizing 3D Body Scanning for Research and Industry
3D body scanning lends itself to a wide variety of fields. Healthcare professionals can use body scans to make 3D printed prosthetics, animation studios can use body scans for highly-accurate portraits, ...
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 ...
Photodynamic Therapy: Targeting Cancer with Light
How research in photodynamic therapy may lead to new treatments of deadly diseases like cancer. Mesothelioma is a form of cancer that is most often associated with asbestos exposure. Despite efforts of ...
The Importance of LiDAR in Self-Driving Cars
Autonomous vehicles are a scientific wonder that optics is turning into a reality. On top of being highly convenient, autonomy for vehicles can potentially reduce rates of collision. This article covers ...
