Abstract
An optical method for in- plane rotation angle measurement based on hardware sampling moiré is presented. This method is investigated and introduced as a new technique for in- plane rotation angle measurement. Equations are derived and theoretical calculation and experiment are done base on these. Experimental results confirms that measurement accuracy in order of 0.1 degree conform to expectance results. Advantages of this technique are simplicity, high sensitivity and measurement and direction determination of rotation angle in the same time.
