Abstract
We formulate a four-dimensional (4-D, space-time dimension) image formation theory of all laser microscopy and optical coherence tomography (OCT) by using 4-D Fourier optics. We define a Fourier transform pair: a 4-D amplitude spread function in space-time domain and a 4-D aperture in spatiotemporal frequency domain. To calculate the 4-D aperture, we also define 4-D pupil functions that include the information on light source spectra in addition to NAs of excitation and detection systems in microscopy. The 4-D aperture is a new concept indicating the sensitivity to object frequencies that contribute to the image formation in microscopy including OCT.
