The linear Fresnel reflector solar technology suffers from the lack of optical precision, due to the dynamic change of optical distance brought about by the rotation of the mirror strips. We propose a simple method to produce mirror strips with dynamic curvature of high precision, which can be used to significantly enhance the optical concentration efficiency of linear Fresnel reflector solar concentrators. The basic idea is to create a dynamically modifiable depression behind the mirror, that curves the mirror through the elastic deflection of the mirror's substrate.
