Abstract
In order to optimize an omni-direction laser warning system based on diffusive reflection detection,using the method of theoretical derivation and experiment analyzing,the imaging rule of a fish-eye lens was deduced and discussed by means of theoretical derivation and experiment.The power function of the receiving signal was deduced.The illumination uniformity of the image-plane and imaging characteristics of CCD were discussed.The formula of the number of imaging elements was deduced.For different imaging elements,the power formula of one imaging element was put forward.The graphs of relation between the number of imaging elements and the distance d between the detector and the facula was provided.At different visible range,the graphs of power of one imaging element related with the transmission distance R and with distance d were shown.The obtained results offer performance guidance for design,development and optimization of an omni-direction laser warning system based on diffusive reflection detection.
