There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman spectroscopy and ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: This paper proposes an absolute positioning method for distance encoding by fusing reference signals with incremental signals. Reference marks with extinction characteristics are embedded in ...

Abstract: Following this paper, the design, implementation, and evaluation of an intelligent optical gas leakage detection system based on machine learning and an Arduino platform to enhance the ...
