Summary:Image: Ozcan Lab/UCLA The computational imaging platform is made of inexpensive components, including an image sensor chip - which costs just a few dollars apiece and is like the ones used in mobile phone cameras - and two light-emitting diodes, which are used to illuminate the sample. The two LEDs are positioned outside of the container, and slightly tilted toward each other so that they will cast shadows from the moving sperm cells onto the image sensor. “Because of how the two LEDs are positioned, each individual sperm generates two separate shadows from different angles - each containing holographic information that is used to reconstruct a digital 3D image of the sperm body through algorithms,” says Wei Luo, a former UCLA doctoral student and a co-author of the paper.
