Iranian Researchers Make Microscope to Detect Forgery of Signatures, Writings
“The microscope is used for imaging different samples in 3D,” said Ma’soumeh Nasseri, one of the researchers of the company who participated in designing the 3D optical microscope.
“It takes images of the sample’s surface in different steps and zooms, and based on the software defined for the system. Then the images are combined and provide researchers with a three-dimensional image,” she added.
Noting that the microscope can also be used for crime detection, Nasseri said, “Since the device provides a 3D image, the difference between two writings or signatures can be recognized.”
Nasseri had also earlier announced manufacturing of an Atomic Force Microscope (AFM) for imaging living biological samples.
“The new product of our company, an Atomic Force Microscope, is utilized for conducting studies on biological samples, living tissue and cells,” she said.
“The microscope is used to examine the surface of biological samples, but its difference with other AFMs is that researchers are capable of taking images of the tissue of the sample in liquid environments,” the researcher added.
Nasseri explained that generally, in biological works, a series of tissues should be in a buffer environment so that the tissue remains intact, or in some cases, it is necessary to examine the tissues live, adding that this device allows us to take images of the tissues in the buffer environment and drying the sample is not necessary.
“In addition, this microscope provides researchers with the possibility of imaging the bottom surface of the sample. Once the sample is placed on the slide, it can also be imaged underneath, which is very important in biological studies,” she stated.
