Then, TIPR method using two intensity measurements (one of the two intensity measurements is recorded in the Fourier domain and the other is estimated in the spatial domain from the first step) is used to recover the phase in the spatial domain.
(5) The classical TIPR algorithm using the recorded Fourier amplitude [A.sub.2] and the estimated amplitude [absolute value of [g.sup.est](x, y)] from the first step is used to iteratively recover the phase in the spatial domain.
However, in the second step (i.e., TIPR) of the TSPR, the SNR of the phase recovered increases as high as 45 dB.
The purpose of Experiment 3 is to compare the performance of phase retrieval between our TSPR method and the other two algorithms (TIPR algorithm and SIPR algorithm) under different sampling rates.
As shown in Figures 10 and 11, the TIPR method is the best, the TSPR method is the second, and the SIPR method is the worst.
"We are very excited to have BCI on our team," said Don Arturo Diaz, president and founder of Empresas Diaz and Developer of TIPR
. "Their extensive experience in the Caribbean and surrounding region played a key role in our decision to bring them on board.
