The origin and nature of the highest-energy cosmic rays remain a puzzle. A critical concern is the composition of primary cosmic rays at energies above 10^19 eV, where the GZK cutoff should be important. In principle, Cherenkov light generated in extensive air showers can be used to determine the energy and estimate the atomic composition of the primary cosmic rays. We present a study to explore the prospects of using an array of photon detectors to sample the lateral distribution of Cherenkov light arriving on the ground. By measuring the arrival time and photon density of Cherenkov light, we could provide an independent mechanism for reconstructing air shower parameters. We also consider a preliminary design for such an array with initial performance estimates based on Monte Carlo air-shower simulations.
