Researchers from Ben-Gurion University have come up with a new satellite imaging system. It can revolutionize the economies and can even change imagery available from earth-based telescopes and even from space-based cameras.

According to Angika Bulbul, a Ph.D. candidate from BGU states this invention will entirely change the cost of space exploration, aerial photography, astronomy, and more. Bulbul was under the guidance of Prof. Joseph Rosen in the BGU Department of Electrical and Computer Engineering.

How a Small Lens Can Create Images as Big an Area of Mirror

Researchers stated that nanosatellites were the size of milk cartons and were arranged in a spherical (annular) configuration. The nanosatellites were able to capture images who size was similar to that of full-frame. It also had a concave mirror system or lens that used in telescopes nowadays. All these information were published in a paper issue of Optica.  

Bulbul further added by saying some of the former assumptions related to long-range photography was incorrect.  She further added by saying one only require a small part of a telescope lens to find quality images. Even if the perimeter aperture of a lens may it be as low as 0.43 percent, still image resolution can be similar to that of full area of mirror/lens-based imaging systems. Therefore, by using this nanosatellite huge costs can be reduced. Moreover, material and time required for huge conventional optical space telescopes with huge curved mirrors can also be saved.  

Furthermore, to demonstrate the SMART system capabilities, the research team built a small laboratory model. The model has a circular arrangement of sub-apertures to learn about the image resolution and then relate them with imagery drawn through full lens.
