An optical guidance system for guiding a projectile is disclosed. The optical guidance system includes a laser, a first and second cylindrical holographic lenses and a variable zoom lens. The laser generates a laser beam, and the first and second cylindrical holographic lenses transform the laser beam into a x-direction and y-direction scan patterns, respectively. The variable zoom lens projects the x-direction and y-direction scan patterns in the form of multiple scan fields, each within a scan corridor, in order to guide a projectile along a flight path towards a target.
