Embodiment Construction

[0020] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0021] refer to figure 1 As shown, the present invention forms a silicon lens array by splicing multiple silicon lenses, and a planar antenna array is placed in the center of each silicon lens, and a large-scale terahertz focal plane array is formed by combining the planar antenna array and the silicon lens array. This method effectively overcomes the shortcomings of a single silicon lens with a small field of view and cannot realize a large-scale array. On the other hand, it has the advantages of low processing difficulty, flexible configuration, and unlimited array size. It has application prospects in the field of terahertz imaging. . This paper also gives an example of the optical design of a 1024-pixel terahertz focal plane array applied to astronomical observation.

[0022] The optical layout of the terahertz focal plane array des...

Abstract

A terahertz focal plane array disclosed by the present invention is characterized by comprising a plane antenna array and a first lens array connected with a plane lens array. The present invention also discloses a design method of the terahertz focal plane array. The terahertz focal plane array and the design method of the terahertz focal plane array of the present invention effectively overcome the disadvantages that the field of view of a single silicon lens is smaller, and the large-scale arrays can not be realized, on the other hand, also have the advantages that the processing difficulty is low, the configuration is flexible, the array scale is not limited and the like, and have the wide application prospect in the terahertz imaging field.

Description

technical field [0001] The invention relates to a terahertz focal plane array, in particular to a terahertz focal plane array based on spliced ​​silicon lenses. The invention also relates to a design method of the terahertz focal plane array. The invention belongs to the research field of terahertz detection technology. Background technique [0002] Terahertz focal plane arrays are widely used in the fields of terahertz astronomy, medical imaging and public safety. The coupling between the terahertz detector array and the external electromagnetic signal is usually completed in two ways, one is to use a metal feed horn array, and the other is to use a combination of a planar antenna and a dielectric lens (usually silicon material) The quasi-optical antenna array, in which the advantages of the quasi-optical antenna are that the physical size of the array is more compact, the manufacturing cost is lower, it is easy to integrate on a large scale, and it can be easily integrat...
