A system is presented for collecting and concentrating light from a moving light source (e.g. the Sun). The system comprises at least one anamorphic optical element, defining an optical axis and a projection region and having a predetermined effective aperture which defines primary and secondary axes. The effective aperture is configured for collection of optical radiation arriving from a predetermined solid collection angle defining a first range of angles with respect to a plane spanned by said optical and primary axes. The anamorphic optical element is configured such that light passing through said effective aperture within a predetermined first range of angles within said predetermined solid collection angle is concentrated onto at least a part of said projection region. At least one receiver aperture is defined by at least a part of said projection region.
