It can be seen that the integral in the above equations is the Fourier transform of the aperture function evaluated at frequencies = / = / = / = / Thus, we can also write the equation in terms of a Fourier transform as:
Companies commonly offer paid vacation time as a benefit of employment. Whether you have a few days or a few weeks, your time off must first get approved by your supervisor.
