A high-resolution retinal imaging camera is described that uses a Shack–Hartmann wave-front sensor and a Fourier deconvolution imaging technique. The operation of the camera is discussed in detail and high-resolution retinal images of the human cone mosaic are shown for a retinal patch approximately 10 arc min in diameter from two different retinal locations. The center-to-center cone spacing is shown to be ∼2.5 μm for the retinal images recorded at 2° temporal from the central fovea and ∼4 μm for the retinal images recorded at 3° temporal from the central fovea.
