Paper Abstract

We present an optical system with four lenses that imitate the eyes of a dragonfly. With these lenses, an attempt is made at simultaneous 360° viewing without any translation, rotation, or scaling. The viewed image will be projected onto a 2D image. The dragonfly eye system inspired earlier work by Luke and others. They achieved a wide viewing range through compound eyes. However, their work fell short of a perfect 360° circular viewing field. In this paper, a simultaneous 360°-wide vision system and representation of the simple still image is attempted. This is done through appropriate combinations of the compound eyes' hemispheres and the location settings at 45°, 135°, 225°, and 315° on the sphere. This covers the entire visual volume that includes the observer. The observed subject can be represented as a simple planar image. The result shows that within the circular imaging area, the four ellipses along each edge of the lozenge, composed of the four points of the compound eyes at 45°, 135°, 225°, and 315°, provide outer vision areas and the remaining regions constitute the inner visual field. By proper adjustment of the initial positions of the lenses, a doughnut shape is produced. Our approach is computational in nature. The proposed optical system can be an effective tool in medical or military applications.
