Abstract
We propose to modify the solar collector PETAL (Photon Energy Transformation & Astrophysics Laboratory) for astronomy. The mirror is a segmented parabolic dish collector, which has a relatively poor imaging quality. The conversion can be done by either of two principal methods: (1) phasing the surface of the collector itself or significant sections thereof: (2) transforming the structure into an optical interferometer by mounting small telescopes around its rim, and using fibre optics to combine the light at a common focus.
