I would like to have entitled this article 'What is Dip Moveout?' but then I would have to admit that there is more than one answer. If we turn to the text book on Applied Geophysics by Telford et al. (1976), we find the original classic definition has to do with the effect of dip on the timing of events on shot records.

Reliability assessment of integrated power transistors: Lateral DMOS versus vertical DMOS
Microelectronics Reliability, 2008The total safe operating area of both lateral and vertical integrated DMOS power transistors is evaluated. The electrical, hot carrier and thermal safe operating area of both devices types is investigated, and a comparison is made. It is found that the vertical DMOS exhibits a superior hot carrier and electrical safe operating area, mainly being due to

Born DMO (BDMO) is a method of transformation of finite offset data to zero offset data The method cascades an inversion of offset data to produce a subsurface model with a generation of zero offset data from the resulting model. Both the inversion and the modeling steps are based on a Born approximation for modeling wave prop% g&ion, hence the name ...

Dip MoveOut (DMO) is a standard step in processing of modern reflection seismic data. It plays an important travel time and amplitude role in preparing the data for migration.

When we were deciding which topics to cover in this book, we came to a point where we wanted to try something a little adventurous. Mark suggested that maybe we should include replication. After I got my breath back, we both agreed that replication would be in the book.

Piezoelectric DMOS strain transducers
Applied Physics Letters, 1976High-frequency strain transducers consisting of n-channel piezoelectric DMOS transistors have been constructed. These transducers have detected surface acoustic waves at 20 and 28 MHz. The transducers exhibit gauge factors of the order of 105 at dc.

The construction of a 3-D Kirchhoff dip moveout (DMO) operator for the constant‐velocity case is remarkably simple in concept. First, generate the 2-D DMO operator between the source and receiver and then place it in the desired output 3-D volume along the trajectory between the source and receiver.

The seismic industry applies dip moveout (DMO) processing increasingly often to correct for the up-dip reflection point smear inherent in common midpoint (CMP) 3-D seismic surveys. Successful DMO application requires a complete reconstruction of a wave field by shifting and summing energy along sourcereceiver azimuths dependent upon the 3-D survey ...

We propose a new dip-moveout (DMO) processing technique, an integral DMO method in the Radon domain called Radon DMO, which is especially applicable to irregularly sampled 3D datasets. Radon DMO offers several advantages for processing surveys with less than ideal design or acquisition characteristics, common problems for land 3D surveys in particular.
