A new technology called FINCH (Fresnel INcoherent Correlation Holography), invented by researchers at Johns Hopkins University and Ben-Gurion University of the Negev, could make three-dimensional imaging quicker, easier and less costly than current methods. According to Gary Brooker, director of Johns Hopkins University's Microscopy Center and a co-inventor of this new technology, the FINCHSCOPE, a 3-D microscope built using FINCH technology, uses microscope objectives with the highest resolving power, a spatial light modulator, a charge coupled device (CCD) camera, and some filters to acquire 3-D microscopic images without having to scan multiple planes.

"Normally, 3-D imaging requires taking multiple images on multiple planes," stated Brooker, a research professor of chemistry in Krieger School of Arts and Sciences. "For this reason, holography currently is not widely applied to the field of 3-D fluorescence microscopic imaging." Brooker also believes the technology could one day lead to 3-D video. "With traditional 3-D imaging, you cannot capture a moving object," he explained. "With the FINCHSCOPE, you can photograph multiple planes at once, enabling you to capture a 3-D image of a moving object."

FINCH technology could have numerous applications in the medical field including endoscopy, ophthalmology, CT scanning, x-ray imaging, and ultrasounds. Another potential application may be homeland security screening.
