An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

As the U.S. Army produces third-generation forward-looking infrared (FLIR) sensors, officials are exploring emerging capabilities that might be integrated into fourth-generation systems. FLIR ...

The Defense Advanced Research Projects Agency (DARPA) has announced a new program which seeks to enable quantum-level infrared (IR) detection at room temperature. The IR spectrum is a vast information ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

Infrared sensors, which act as the "seeing" component in devices such as LiDAR for autonomous vehicles, 3D face recognition systems in smartphones, and wearable health care devices, are regarded as ...

Aberdeen Proving Ground, MD -- For centuries, warfighters have used obscurants like smoke to evade enemies and stay safe on the battlefield. As technology advances and new threats emerge, older ...
