| Abstract: | The research background, system advantages, and current status of fiber-array imaging laser radar are introduced firstly. We present a design scheme of the system and introduce its principle. Window scanning on fiber array is used to avoid fabricating electrophotonic detector arrays and to reduce the number of separate electrophotonic detectors. Every component of fiber-array imaging laser radar is analyzed, including the choice of fiber, the design of fiber array and the analysis of positive lens. The effect of the F number of positive lens on fiber-array receiver is discussed mainly and optimum value of F number is 5.47. The transmission efficiency of fiber-array imaging laser radar is deduced and its expression is presented in the end. |
| Keywords: | fiber array laser radar imaging radar focusing lens transmission efficiency |
