Abstract: A method to obtain the azimuth angle of laser is represented,which can avoid complex computation and complex electric circuit.Furthermore,two means to increase the angular resolution including utilizing laser beam intensity ratio and adding more sensors are described,and the relationship between the angular resolution and lens'parameters with different number of sensors is given.Based on this way,higher angular resolution can be obtained with fewer sensors.
