Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive ...
Abstract: In this paper, a high-precision rotary encoder based on a sinusoidal transmissive pattern (STP) is proposed for detecting shaft rotation. The STP disk can be realized by coating bell-shaped ...
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 ...
