FINCHSCOPE Offers 3-D Holographic Microscopy Imaging

Filed under: in the news...

In the latest issue of Nature Photonics, Johns Hopkins and Ben Gurion University researchers describe their Fresnel incoherent correlation holography (FINCH) technique for imaging objects in 3-D without having to rotate the object with respect to the sensing system.

The FINCH technology and the FINCHSCOPE uses microscope objectives with the highest resolving power, a spatial light modulator, a charge-coupled device camera and some simple filters to enable the acquisition of 3-D microscopic images without the need for scanning multiple planes.

The Nature Photonics article reports on a use of the FINCHSCOPE to take a 3-D still image, but moving 3-D images are coming, said Brooker and co-inventor Joseph Rosen, professor of electrical and computer engineering at Ben-Gurion University of the Negev in Israel.

"With traditional 3-D imaging, you cannot capture a moving object," Brooker said. "With the FINCHSCOPE, you can photograph multiple planes at once, enabling you to capture a 3-D image of a moving object. Researchers now will be able to track biological events happening quickly in cells."
