Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

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 ...

SPIE Photonics West sees the global optics and photonics community come together to present and discuss the latest industry trends and research breakthroughs Photonics focus Researchers, innovators, ...

Abstract: Incremental optical encoders are widely used as photoelectric sensing components in direct current motor servo systems, but their inherent susceptibility to optical interference ultimately ...

Abstract: Given the limitations of traditional feature coding in capturing multiscale information and precise segmentation, existing deep learning-based change detection (CD) methods often suffer from ...

This project implements a real-time closed-loop motor control system where motor speed is dynamically regulated based on obstacle distance. An ultrasonic sensor provides the reference input, an ...
