Radiometric calibration is an essential process that converts raw digital counts recorded by Earth observation sensors into meaningful physical units, such as spectral radiance or top‐of‐atmosphere ...

A new device fingerprinting technique can track Android and iOS devices across the Internet by using factory-set sensor calibration details that any app or website can obtain without special ...

Smartphones rely on multiple sensors—such as the accelerometer, gyroscope, compass, and proximity sensor—to power everyday features. From screen rotation and navigation apps to motion tracking and ...

Calibration is a crucial step in the manufacturing process of many sensors (or transmitters) such as pressure, temperature and position sensors. One key component needed for calibration is the ...

Over time, the performance of optical isolators or sensors can degrade. But a simple auto-calibration circuit will account for changes in LED and sensor characteristics to keep optical devices running ...

O(p2): The quadratic contribution in pressure refers to the nonlinearity error of the reading which is typically in the range of 0.3% full-scale output. The offset ...

An optical phased array (OPA) is a nonmechanical beam-steering control device with high directivity and deflection efficiency. Owing to its high resolution, fast response, and absence of inertia, the ...
