4pi-Steradian Curved And Lensless Imagers (4pi-SCALE) 1.2.2.

We propose a new passive three-dimensional imaging platform that allows the ultimate field of view (FOV) of 4 Steradian, or a complete sphere, while maintaining extremely thin conformal and flexible geometry. Moreover, our platform is capable of produce high quality 3D images in short-wavelength infrared (SWIR). Despite decades of research, current state-of-the-art night vision systems remain bulky, twodimensional, and with a FOV that is significantly smaller than the human vision FOV. We believe that the current imaging platform, which is made of a single lens and focal plane array, faces fundamental challenges with respect to addressing the aforementioned issues. Recent efforts to replace the flat focal plane array with a curved array can address the limited FOV. However, producing high-resolution curved arrays is a significant challenge, and the camera remains bulky and limited to 2D imaging.
