This paper introduces temperature invariant absolute rotatory encoder using photocells on the visible light spectrum. A multivariate function is proposed to remove error arising on photocells through temperature variance and a small change in light intensity. Multiple experiments are conducted in the controlled environment to prove proposed multivariate function. Encoder introduced in this paper is more scalable than grey code encoder available in the market. Dynamic auto calibration is also proposed to make encoders more reliable with time.

在可见光谱上使用光电池的温度恒定和高精度绝对旋转编码器

本文介绍了在可见光谱上使用光电管的温度不变绝对旋转编码器。提出了一种多元函数，以消除由于温度变化和光强度的微小变化而在光电管上产生的误差。在受控环境中进行了多次实验，以证明提出的多元函数。本文介绍的编码器比市场上的格雷码编码器更具扩展性。还提出了动态自动校准，以使编码器随着时间的推移更加可靠。
