The first version of the holographic microscope was made with a relatively low quality camera (compared to the resolution of the camera used in the Super Resolution Microscope), a pinhole, a film canister, and an LED. Even with an incoherent light source in the LED, hologram reconstruction was achieved.

The first holographic microscope.  The LED is turned on and off using an Arduino Microcontroller.

A sample of the hologram reconstruction shows that different beads are in focus at different depths.  Click the picture for a closer view.
