Details regarding the cooperative alliance were reported by the head of the research team on behalf of the Ben-Gurion University, Professor Adrian Stern, and the Vice President & R&D Dean of Ben-Gurion University of the Negev, Professor Dan Blomberg, at the NexTech international advanced technology conference held yesterday at the new high-tech park of Be'er-Sheva, where they also announced the development of an HD spectral sensing system for space mission.

At the foundation of the development effort stands a technology that is not harnessed to the restrictive principles that currently inhibit most imaging systems, so it enables substantially improved performance characteristics. Initially, the research effort included the development of a groundbreaking imaging method, based on a new mathematical theory known as compressive sensing. An experimental process has been completed recently where a compressive imager was designed, implemented and used for photographing various objects using liquid crystals. The results, as expected, demonstrated the numerous advantages of the system compared to systems currently used for imaging, as well as providing the option of capturing images at spectral resolutions that are at least ten times higher than those currently attainable using existing systems.

In this context it was reported that the subsequent phase of the research effort has already been initiated, and at the present time various experiments are being conducted at the Ben-Gurion University. These experiments include the use of miniature resonance-based encoders for hyper-spectral and ultra-spectral imaging intended to be applied on space-borne platforms.

Once the development process has been completed, the imager will be able to take high-resolution images (similar to the resolution of today's monochromatic photography) through hundreds of spectral channels and take advantage of the compressive sensing theory in order to save only 10% of the size of the image as we currently know it.

This cooperative alliance between the ImageSat Company – a leading industry in the field of civil space imaging – and academia has brought the New Space concept, which promotes innovation and creativity in the space industry, to a new high point and will enable the ImageSat Company to establish itself as a global leader in the field of spectral sensing.

The international advanced technology conference held at the high-tech park adjacent to the Ben-Gurion University is an initiative of Israel Defense, the Gav-Yam Negev Technology Park, the Ben-Gurion University of the Negev, the City of Be'er-Sheva and CyberTech.

What Caused the Explosion on the Iranian Tanker

An Iranian merchant ship was damaged last week while sailing off the shore of Saudi Arabia, and since then, an attempt has been made to understand who attacked the ship and how they did it. According to various reports, the ship was attacked by missiles, but photographs of the ship after the attack have suggested some other options. Commentary
