Paper Abstract

We report on approaches of pulsed digital holographic recording and its relevant digital reconstruction based on Fourier optics for measurements of high resolution in time domain or in space domain, in which angular division multiplexing system is respectively employed to record multiple images in a single frame of a CCD. This new approach can be used to record either a series of images in an ultra-fast process with high resolution in time domain, or to record a transparent object with super-resolution in space domain. In the digital reconstruction process, Fourier transformation and frequency filtering in the Fourier plane will be employed to separate the spatial spectra of the multiple recordings, and each of the reconstructed images can be displayed individually with a time resolution of the femto-second order or fused into an image of the object with a synthetic aperture.
