Satellite-based electro-optical sensors are intended to detect missile launches early on, gaining valuable time for initiating countermeasures in case of an attack. The Fraunhofer Institute of ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

Apple has filed for a patent (number 20210157414) for an “optical sensing device” that involves an Apple Watch that can recognize gestures. In the patent filing, the tech giant optical sensors for ...

Apple is working on new fingerprint sensing technology that could work through an iPhone display by taking advantage of off-axis angular light. In a new patent application, Apple hones in on optical ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...
