Abstract

A bionic optical compound eye of an integrated structure belongs to a microstructural optical component and an application field of the microstructural optical component. The bionic optical compound eye is arranged in an ommatidium array according to certain geometric rules of hexagons, squares and the like. Ommatidiums include a micro lens, a crystal cone and a cylindrical waveguide which are coaxial and arranged along the optical axis or the Z axis from the left to the right. No physical distance is arranged between the plano-convex lens and the crystal cone and between the crystal cone and the cylindrical waveguide along the Z axis so as to form a whole. The micro lens can be seen as a plano-convex thin lens. The length from the top end of the micro lens to the tail end of the crystal cone is the focal length of a spherical refraction surface having the same curvature radius and refraction rate as the micro lens sphere. An image space principal point and a focal point of the ommatidiums of the integrated bionic optical compound eye are closely relevant to the length of the cylindrical waveguide. By applying the bionic optical compound eye of the integrated structure to a photoelectric detection system, a photoelectronic imaging system and the like, the system size can be reduced, the system weight is reduced, and complexity of coupling of the bionic optical compound eye with an image sensor or a photoelectric detector can be reduced.
