Moreover, unlike night-vision goggles, which amplify light to detect low-level infrared signals, the lenses allow users to see only intense infrared signals, such as those emitted by light ...

Rabbitt figured out how to use infrared light to send signals to the brain. Instead of using electrical signals, pulses of invisible wavelengths activate nearby nerve cells and communicate with ...

(Nanowerk News) A team of researchers has developed a device that uses the material graphene to detect mid-infrared light and efficiently convert it to electrical signal at room temperature. It’s a ...

as well as options for light pipe lengths and diameters. The flexibility of design allows for efficient customer-specific solutions while enabling increased opportunity to signal status ...

Instead, it is powered by the same infrared ... an output wakeup signal.” The sensors are based on tiny mechanical switches that are triggered by specific wavelength of lights.
