Aim\ To study the feasibility of the structure of a square effective screen area at the center of a square frame of the laser screen system for projectile velocity measurement. Methods\ By the optical path analysis of single cylindrical reflector scheme and double cylindrical reflectors scheme respectively, the main parameters are selected and the rationality are varified by the aberration analysis. Results\ Both of them satisfy the demand that a square effective screen area are geometrical similar to the frame and at the center of the frame. Conclusion\ Both single cylindrical reflector scheme and double cylindrical reflectors scheme are feasible. The offer the foundation for the design of laser screen systems for large calibre projectiles.
