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 ...

Featuring a terrific central performance from Riz Ahmed, ‘Relay’ is styled very much in the mold of classic paranoid thrillers from the 1970s like ‘The Parallax View’ and ‘The Conversation.’ It’s not ...

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...

US defence giant RTX feels that advanced electro-optical/infrared (EO/IR) sensors are now well positioned for detecting unmanned air vehicles (UAVs), missiles, and aircraft at extreme ranges. In the ...

According to Xiaomi’s posters, the Xiaomi 15 Ultra will debut a new “Leica Ultra-Pure Optical System,” designed to enhance image clarity and light intake. The device is codenamed “Night God,” ...

The NBA's 2025 All-Star Weekend has arrived. We saw the Rising Stars Challenge on Friday night and Mac McClung win the Dunk Contest for the third year in a row (and some Skills Challenge Controversy) ...

Imagine a long, dank pre-dawn to post-dusk day of crawling up an exposed mountainside, trudging through snow and slop, and battling relentless horizontal sleet and snow head-on. If you still have your ...

Infrared (IR) detector manufacturer SemiConductor Devices (SCD) has seen a significant increase in European demand for its products in the wake of the Russia-Ukraine war, the company has told Janes, ...

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 ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...
