A groundbreaking phase imaging method, resistant to phase noise and effective in dim light, has been developed by international researchers. This technique, detailed in Science Advances, enhances imaging capabilities in fields ranging from medical research to art preservation. (Artist’s concept.) Credit: SciTechDaily.com
Innovative quantum-inspired imaging technique excels in low-light conditions, offering new prospects in medical imaging and art conservation.
Researchers at the University of Warsaw’s Faculty of Physics with colleagues from Stanford University and Oklahoma State University have introduced a quantum-inspired phase imaging method based on light intensity correlation measurements that is robust to phase noise. The new imaging method can operate even with extremely dim illumination and can prove useful in emerging applications such as in infrared and X-ray interferometric imaging and quantum and matter-wave interferometry.
Revolutionizing Imaging Techniques No matter if you take photos of a cat with your smartphone or image cell cultures with an advanced microscope, you do this by measuring the intensity (brightness) of light pixel by pixel. Light is characterized, not only by its intensity but also by its phase. Interestingly, transparent objects can become visible if you’re able to measure the phase delay of light that they introduce.

Archaeologists conducting works at the Temple of Hatshepsut have made new discoveries in a subterranean tomb.
The temple was constructed during the reign of Pharaoh Hatshepsut of the Eighteenth Dynasty of Egypt. It is situated opposite the city of Luxor and is considered a masterpiece of ancient architecture, with its three terraces rising into the cliffs of Deir el-Bahari.
Since 1961, efforts from a Polish-Egyptian archaeological expedition have been working to conserve the temple, with more recent works by a team from the Centre of Mediterranean Archaeology (CAŚ) from the University of Warsaw.
Recently, CAŚ members have been working to document and restore a chapel dedicated to Hathor, in which beneath lies a rock cut tomb with a 15-metre-long corridor and burial chamber left untouched by archaeologists since the tomb was first documented by Henri Édouard Naville in the 19th century.

The team discovered that the tomb contained tons of debris, in which several hundred artefacts were found that date from either the Middle Kingdom when the tomb was constructed, or from the later 18th Dynasty in the New Kingdom period
Dr. Patryk Chudzik from CAŚ reported that the tomb was built next to the temple of Pharaoh Mentuhotep II, in which the interred was likely someone closely related to the pharaoh. “The number and quality of the monuments we found are amazing. They include a wooden figurine, most probably the owner of the tomb, with a wig on his head” said Chudzik. READ MORE...
