使用高性能和非常紧凑的加速度计的角度测量设备提供了用于生产高度紧凑和精确的角度测量设备的新的和令人兴奋的方法。加速度计是微加工的，能够以非常高的精度测量加速度。通过使用重力作为参考，这些紧凑的设备也可以用于测量旋转角度。这些器件的固有问题是它们的响应特性随温度变化，这对测量精度是有害的。本文介绍了一种有效的方法来克服这个问题，使用温度传感器和智能软件来补偿这种漂移特性。为了证明这项工作的有效性，实验已经开发和进行的结果和分析提供在本文的最后讨论。
An angle measuring device using a high performance and very compact accelerometer provides a new and exciting method for producing highly compact and accurate angle measuring devices. Accelerometers are micro-machined and are able to measure acceleration to a very high accuracy. By using gravity as a reference these compact devices can also be used for measuring angles of rotation. The inherent problem with these devices is that their response characteristic changes with temperature which is detrimental to measurement accuracy. This paper describes an effective method to overcome this problem using a temperature sensor and intelligent software to compensate for this drift characteristic. In order to demonstrate the effectiveness of this work, experiments have been developed and conducted with the results and analysis provided at the end of this paper for discussion.
