    • An optical tracking system is disclosed that provides more precise tracking and better performance in an optical mouse. It involves provides a collimated laser, and imaging a reflection of the collimated laser, such that the reflection has a substantially linear phase gradient. The reflection of the laser includes a pattern of speckles due to optical interference effects. The speckles are imaged such that the substantially linear phase gradient restricts any variation in intensity of the imaging of the speckles during a translating motion of the reflection, thereby providing superior tracking performance.
    • 公开了一种光学跟踪系统,其在光学鼠标中提供更精确的跟踪和更好的性能。 它涉及提供准直激光,并对准直激光的反射进行成像,使得反射具有基本上线性的相位梯度。 激光器的反射包括由于光学干涉效应引起的斑点图案。 斑点被成像,使得基本上线性的相位梯度在反射的平移运动期间限制斑点成像的强度的任何变化,从而提供优异的跟踪性能。
