It’s a soap foam selfie!

Andy Resnick, Ph.D., of Cleveland State University made this remarkable photograph of soap bubbles (magnified 4x) using an imaging technique known as reflection differential interference contrast.

It splits the illuminating light into two overlapping beams. The amount of separation of the beams is very slight — below the resolution limit of the lens.

“The interference of the two reflected beams results in image brightness being proportional to the surface slope,” said Dr. Resnick, assistant professor of physics at CSU.
