Recognizing the features and benefits of each type of light sensor will allow for the proper selection in specific requirements. The three most common photodetectors are the photomultiplier (PMT), the ...

Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world's smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a ...

What is a SWED? How the research team's SWED design significantly improved imaging. Initial test results with the SWED design. The standard two-dimensional array of piezoelectric sensors used for ...

Atmospheric Light Detection and Ranging (LIDAR) is widely used in aviation and aeronautic applications. LiDAR applications are not only used as tools for scientific studies but also to improve flight ...

As photonics technology becomes increasingly sophisticated, optical measurements grow increasingly complex. To make reliable measurements, one must consider the characteristics and interactions of ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...
