The shadow imaging hack to avoid lenses reminds me of the single-pixel camera that produces the image via random sampling http://www.ece.rice.edu/~duarte/images

- teaspoon 16y agoThere's also the optofluidic "microscope-on-a-chip": http://deviceguru.com/cal-tech-unveils-microsopic-microscope/ http://deviceguru.com/cal-tech-unveils-microsopic-microscope... The lensless optics are similar to the cellphone microscope, except that there is virtually no distance between the sample and the sensor. Also, the sensor is a one-dimensional array of CCDs; the sample is "scanned" by propelling it over the array in a stream of fluid.
