Fiber-optic sensor reads strain through electrical signals, skipping optical analyzers
Scientists have demonstrated a new fiber-optic sensing method that detects strain and displacement by reading interference patterns directly in the electrical spectrum of a photodetected signal. The ...
I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
Prof. Jong-Soo Lee’s team realizes a “hybrid photosensor” combining quantum dots and two-dimensional semiconductors - Proposes a low-cost, large-area platform to replace expensive conventional sensors ...
ARLINGTON, Va.--(BUSINESS WIRE)--Leonardo DRS, Inc. (NASDAQ: DRS) announced today that it has been recognized with the prestigious 2024 Herschel Award for the development of a groundbreaking cooled ...
Acoustic MXene plasmons detect weak molecular fingerprints in nanometer-thick films while extending infrared sensing into the short-wave infrared.
Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...
For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...
(Nanowerk News) The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with ...
