An array crystal module comprises a plurality of unit crystal strips (10). The exterior three-dimensional shape of the array crystal module is a frustum (12) or a combination of a right quadrangular prism (11) and the frustum (12), and the frustum (12) is used to be coupled with a photoelectric device (20). The frustum (12) comprises a first bottom face coupled with the photoelectric device (20) and a first top face opposed to the first bottom face, and the area of the first bottom face is smaller than that of the first top face. A fabrication method of the array crystal module includes: fabricating a crystal strip blank to obtain a unit crystal strip, performing the die cutting to obtain a unit crystal strip in the shape of a frustum or a unit crystal strip in the shape of a combination of a right quadrangular prism and a frustum according to a set obliquity and the thickness of the right quadrangular prism part, and assembling the unit crystal strips together to form an array crystal module. The above array crystal module, on the premise that the detection efficiency is guaranteed, can solve the problem of the light output loss of the crystal caused by the fact that the effective detection area of a photoelectric conversion device is smaller than a packaging area, thereby guaranteeing the sensitivity and performance of a detector. |
