摘要：
The image reconstruction algorithm for spectral analysis approaches the projection vector of image function by means of the projection vectors for various orthogonal-based functions in 2-D Fourier series. The weighting coefficients of various orthogonal-based functions are obtained by using optimization rule. The original image function can be reconstructed through Fourier inversion. The computer simulation shows that the algorithm reconstruction time is less than 1 second. The maximum error less than 5% and average error less than 1% can be obtained through selecting suitable approximate series and image reconstruction for complex field.
