Aiming at the calibration problem existing in the grating target,photoelectric coordinate sensors are designed and applied.By describing the principle of photoelectric coordinate sensors in detail,photoelectric switch model is set up.The scheme avoids the requirements which ask for the radiation brightness and the emission angle to be uniform.Experimental results proved that the scheme of the coordinate sensor is feasible and the parameters selected are reasonable.The design has the advantages of easy making,high precision and low cost.The shot indicating precision is effectively improved.
