Color sensors for better vision

CMOS image sensors in special cameras -- as used for driver assistance systems -- mostly only provide monochrome images and have a limited sensitivity to light. Thanks to a new production process these sensors can now distinguish ...

An ultracompact multimode meta-microscope

Versatility and miniaturization of imaging systems are of great importance in today's information society. Microscopic imaging techniques have always been indispensable for scientific research and disease diagnosis in the ...

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 ...

Arapuca device for international neutrino experiment is enhanced

A critical part of one of the largest recent particle physics experiments was developed in Brazil. The Arapuca is a light detector to be installed in the Deep Underground Neutrino Experiment (DUNE), a project seeking to discover ...
