Problems solved by technology

The arrangement of these two existing lobster-eye lens microchannel tubes is not ideal. The square arrangement will cause uneven distribution of the light participating in the imaging on the image surface, and the circular arrangement will have a large gap in the lens space. , wasting limited space on the lens
Therefore, the existing arrangement of lobster eye structures results in uneven energy distribution and low energy when imaging light.

Embodiment Construction

[0018] Such as image 3 As shown, the sunflower-shaped lobster eye lens has a plurality of microchannel units, and the center of each microchannel unit has its own polar coordinates on the entire lens surface, and each microchannel unit is placed on its own coordinates:

[0019] r = c n

[0020]

[0021] Where r is the polar coordinate radius, θ is the polar coordinate angle, and c is the scale constant, which is related to the edge size d of the microchannel, which should satisfy the condition of c<0.5966d.

[0022] When the lobster eye lens is arranged according to the sun flower arrangement, it will produce the golden section ratio relevant traits.

[0023] The arrangement pattern of the lobster-eye lenses in the sunflower-shaped arrangement conforms to the Fibonacci sequence. On the sunflower-shaped lobster-eye lenses, each microchannel will form two curves starting from the center, and the two curves wil...

Abstract

The invention relates to a lobster eye lens in sunflower-type arrangement and belongs to the technical field of optical components. In order to control distribution of imaging energy to obtain an image with uniform energy distribution, and to fill more microchannel pipes in a limited lens space to improve capacity of collected energy, the lobster eye lens is provided with a plurality of microchannel units. The center of each microchannel unit has polar coordinates on an integral lens surface, and the microchannel units are arranged on the respective polar coordinates, wherein r is the radius of the polar coordinates, theta is an angle of the polar coordinates, and c is a dimension constant. Compared with existing lobster eye lenses, the lobster eye lens can have more microchannel pipes arranged in the same area, and incident energy can be effectively utilized; due to spiral arrangement of the microchannels, more uniform energy distribution on the image surface can be realized, and cross imaging on the imaging surface is avoided.

Description

technical field [0001] The invention relates to a sunflower-shaped lobster-eye lens, belonging to the technical field of optical elements. Background technique [0002] The existing optical system is limited by a single optical axis, resulting in a limited field of view of the system. If the field of view is increased, the image quality will drop rapidly. How to enlarge the field of view of the optical system as large as possible without reducing the image quality has always been a difficult problem in the field of optics. [0003] Lobster eyes are imaged using the principle of reflection. The structural form of the lobster eye is a rectangular prism structure. After the parallel light is incident, it is reflected to the focal plane through the inner wall of the prism. Such a lobster-eye structure has two important characteristics: First, this lobster-eye optical system is derived from the visual system imitating a lobster, and is composed of slightly incident mirrors wit...
