Fiber optics: hair-like human detection imaging equipment

According to foreign media reports, scientists at the University of St Andrews in the United Kingdom have made major breakthroughs in the field of medical equipment. Doctors will be able to “enter” the imaging equipment that is thinner than a person’s hair, into areas that are extremely difficult for humans to reach. In order to see the health of the site.

According to reports, Dr. Tomas Cizmar and Prof. Kishan Dholakia have developed a new technology that for the first time allows accurate images to be transmitted through a single strand of microcables.

For a long time, researchers have been hoping to use thin fibers for image transmission, but the result of many attempts is always cluttered image signals. However, Dr. Sisma and Prof. Dolacchia have now found a way to interpret these cluttered optical signals to form clear and accurate images.

It is reported that their breakthrough progress has laid the foundation for the development of new, cheap, and less harmful imaging equipment, while at the same time allowing medical imaging equipment to “reach” more difficult-to-reach parts of the body for neuroscience. The study of sub-disciplines and other medical disciplines is particularly advantageous because the parts of the body to be studied in these disciplines are either very delicate or difficult to reach.

According to the researchers, fibers that can support multiple modes of optical transmission usually disperse the beam and generate random, elusive signals. In general, this is an imaging problem because light is distorted and lost during transmission. However, scientists at the University of St. Andrews found that if the randomness of light in the fiber can be characterized, the way the image is confused can be predicted. In other words, the output light signal can be interpreted correctly, resulting in the original image.

Dr. Sisma said: “The comprehensive interpretation of random optical signals is an early but progressive method. Since the first experiments, this method has only been used for several years, but we have witnessed a series of very The achievement of our hope. Our new result marks our branch of this discipline has taken a new step in the field of biomedicine, and we look forward to further improvement of technology in the future. It will be an exciting time."

The University of St. Andrews hopes to further study on the basis of the current results, and has now begun to raise funds to support biomedical research in the field of analytical imaging and neuro-opto-electronics science and to celebrate the 600th anniversary of the University of St Andrews. According to reports, the new cooperative research project will push existing research to a higher level, thus opening the door to improvement in the understanding and diagnosis of various diseases.
