| Abstract: | According to the characteristic of the linear array diode laser used in laser fuze system,the way of second-order moment based on CCD is used to measure the beam width.The image processing is discussed,which is the key component in the measurement.To mitigate the influence of CCD noise,a new adaptive integral algorithm is presented,which can obtain appropriate range to integrate light distribution.The result indicates this measurement method is feasible. |
