Mozaffarzadeh, M. (author), Varnosfaderani, Mehdi H.H. (author), Sharma, Arunima (author), Pramanik, Manojit (author), de Jong, N. (author), Verweij, M.D. (author)In acoustic-resolution photoacoustic microscopy (AR-PAM) systems, the lateral resolution in the focal zone of the ultrasound (US) transducer is determined by the numerical aperture (NA) of the transducer. To have a high lateral resolution, a large NA is used. However, the larger the NA, the smaller the depth of focus [DOF]. As a result, the...journal article 2019

Slob, E.C. (author), Wapenaar, C.P.A. (author)We present a three-dimensional scheme that can be used to compute the electromagnetic impulse response between any two subsurface points from surface reflection data measured at a single surface of a lossless medium. The scheme first computes a virtual vertical radar profile using the Marchenko scheme from which focusing wavefields are...conference paper 2017

Van der Neut, J. (author)With seismic interferometry or the virtual source method, controlled sources can be redatumed from the Earth’s surface to generate so-called virtual sources at downhole receiver locations. Generally this is done by crosscorrelation of the recorded down-hole data and stacking over source locations. By studying the retrieved data at zero time lag,...journal article 2012
