Systems and methods for scattering or deviating a laser beam are provided. A system utilizing a lenticular sheet and a laser source projecting a laser beam onto the lenticular sheet produces shapes such as laser cones. Minor adjustments of the laser source with respect to the lenticular sheet may vary the size and shape of the laser cone that provides for improved Light Detection and Ranging (LIDAR) systems. A diffraction grating added in the path of the laser beam causes a laser pattern of a matrix of lines to be produced which also provides for improved. Interference between multiple lenticular sheets may be used to deviate a laser beam to protect military assets from laser-guided projectiles and/or laser acquisition.
