Sub-gram-scale 2 megapixel cameras are currently widely available at very low costs. The trend has been a doubling of pixels for the same mass every two years. It is anticipated that these devices will continue this trend for some time. Advances in planar Fourier capture array cameras should make it possible to eliminate the need for focusing optics in the cameras. Advances in Fresnel lens imaging and planar Fourier capture array cameras should make it possible to build focusing optics in the cameras light enough to be used in the mission, or eliminate the need for focusing optics altogether.
