Windows/OS X: Your computer’s webcam can be useful for more than just quick photos and video calls. The Webcam Pulse Detector is a fun, open source application originally designed at NASA to use your ...

Gentec-EO’s QE12HR and QE25HR pulse energy detectors are designed for use with Q-switched lasers and pulsed laser diodes. These laser energy detectors feature an improved temporal response to ...

Metal detecting is a fun hobby for some, and a serious passion for others, so here's a primer for the newly interested ...

With a 200 foot depth rated housing and a 6 foot maximum detection range, the Pulse 8X from JW Fishers is the company's top of the line detector. It's heavy duty construction and high sensitivity make ...

Most consumer metal detectors find coin-sized objects 8–16 inches deep, but pro models can find items several feet down. In ...

Tsukuba, Japan—Researchers from the University of Tsukuba have shown how adding a tiny resonator structure to an ultrafast electron pulse detector reduced the intensity of terahertz radiation required ...

There are many ways to detect a heartbeat electronically. One of the simpler ways is to take [Orlando’s] approach. He’s built a finger-mounted pulse detector using a few simple components and an ...

Researchers have built a tiny butterfly-shaped optical resonator to improve the sensitivity of ultrafast measurements of electron beam pulses. They found that the enhancement allows less intense ...
