Compact cellphone microscope

This novel approach to cellphone microscopy from Dr. Aydogan Ozcan from the University of California, Los Angeles, foregoes bulky lenses and magnifies electronically.

For this electronic system of magnification, inexpensive light-emitting diodes added to the basic cellphone shine their light on a sample slide placed over the phone’s camera chip. Some of the light waves hit the cells suspended in the sample, scattering off the cells and interfering with the other light waves.
