Linear array push-broom method in laser imaging fuze detection technology

In laser imaging fuze detection technology, a linear array push-broom imaging method was proposed to solve the problem in circle-scan imaging method such as needing scanning mechanism and high pulse repetition frequency laser. The principle of linear array push-broom imaging method was analyzed in detail. Linear array push-broom imaging detection system which consists of linear diode laser array and linear photodiode array was designed to detect tank target. One dimensional scanning was performed by linear array device itself and the other one dimensional scanning was performed by forward velocity of the munition. The image of target was generated based on range information. Basic design parameters of the system including the number of array elements, the size of the image, the pulse repetition frequency and the peak power of linear diode laser array, were chosen based on the calculation of the element laser footprint size. The methods of choosing basic design parameters provide guideline for hardware realization of the system.
