Abstract
The present disclosure provides a method for analyzing the signal of a neutral atom imaging unit, including: preparing a neutral atom imaging unit, which includes a semiconductor detector array and modulation grids disposed at intervals in front of the semiconductor detector array; preparing a neutral atom source plane, energetic neutral atoms emitted by the neutral atom source plane are received by the semiconductor detector array after passing through the modulation grids, and the modulation grids form a projection on the semiconductor detector array; obtaining a response function of the imaging unit according to the projection; calculating the data signal obtained by the neutral atom imaging unit; and performing inversion imaging on the neutral atom emission source according to the response function of the imaging unit and the data signal. The method well inverts the neutral atom emission source to obtain the intensity and size of the neutral atom emission source.
