Having an eye for colors: Printable light sensors

Cameras, light barriers, and movement sensors have one thing in common: They work with light sensors that are already found in many applications. In future, these sensors might also play an important role in telecommunications, ...

Using noise to enhance optical sensing

In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this ...

Slow light to speed up LiDAR sensors development

Quicker is not always better, especially when it comes to a 3-D sensor in advanced technology. With applications in autonomous vehicles, robots and drones, security systems and more, researchers are striving for a 3-D sensor ...

VTT developed an optical fiber made of cellulose

VTT researchers were able to transmit light in wood-based fibre. Optical fibre made of cellulose is best suited for sensors that benefit from the biodegradability of the material. In the future, optical cellulose fibre may ...
