What are the defense applications of electro-optical sensors?

December 30, 2024 By Jeff Shepard

Electro-optic sensors span a wide range of technologies, from various types of imaging devices to infrared (IR) detectors. They are used for various defense applications that enhance situational awareness, including intelligence, surveillance, and reconnaissance (ISR), search and rescue, threat detection and target identification, and protection against IR-guided missiles. Electro-optic and IR (EO/IR) sensors convert electromagnetic […]

What are optical rotary encoders?

September 23, 2024 By Bill Schweber

Accurate measurement of rotary shaft motion, including position, velocity, and acceleration, is crucial in numerous applications. This is typically achieved by incorporating a rotary encoder into the motor or shaft assembly. While “rotary encoder” is often abbreviated to “encoder,” it should not be confused with other electromechanical or electronic encoding devices used for data format […]

Flexible artificial intelligence optoelectronic sensors towards health monitoring

March 11, 2024 By Redding Traiger

Researchers at Tokyo University of Science (TUS) have developed a flexible paper-based sensor composed of nanocellulose and zinc oxide (ZnO) nanoparticles that operate like the human eyes and brain. The sensor is energy-efficient, responds to optical input in real-time, and is both flexible and easy to dispose of, making it ideal for health monitoring applications. […]

What are next generation bio sensing techniques? Part 2

December 13, 2022 By Randy Frank

Part 1 of this blog explored research into localized surface plasmon resonance (LSPR) sensors. This part discusses a surface plasmon resonance/surface-enhanced Raman scattering (SPR/SERS) dual-mode plasmonic biosensor and two other sensing techniques. The SPR/SERS biosensor based on catalytic hairpin assembly (CHA)-induced Au nanoparticle (AuNP) network was proposed for highly sensitive and reliable detection of a […]

What is the difference between an absolute and incremental position encoder?

February 3, 2021 By Randy Frank

Measuring the position of a rotating shaft, speed or direction of motion typically requires a rotary encoder. The two main types of encoding techniques are: absolute and incremental encoders. The absolute encoding technique provides a specific and unique position value for every point of rotation when it is switched on. Absolute encoding is commonly achieved […]
