Abstract
A method for calculating optical aerial images. The method includes following steps. A first pattern distribution in a spatial domain is multiplied by a scaling constant to scale the first pattern distribution to generate a second pattern distribution. A fast Fourier transform is performed on the second pattern distribution to generate a first spatial frequency spectrum distribution in a spatial frequency domain. The first spatial frequency spectrum distribution is multiplied by a pupil function to generate a second spatial frequency spectrum distribution. An inverse fast Fourier transform is performed on the second spatial frequency spectrum distribution to generate a first diffraction image distribution in the spatial domain. The first diffraction image distribution is divided by a scaling constant to scale the first diffraction image distribution to generate a second diffraction image distribution.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
