detect the reflected energy the receivers detect the reflected energy and record a signal corresponding to the capture of the reflected energy this signal is stored either by the receiver itself or may be transmitted to a seismic recorder for storage and later processing the reflected energy is detected by the receiver r 1 by the geophones a and b and is subsequently recorded as traces in a data set the energy detected by the geophone a is illustrated as trea and the reflected energy as captured by the geophone b is indicated in the diagram as treb the subscripts trea and treb also refer to the corresponding traces of the geophones a and b when the seismic energy source 200 is operated in the mode as indicated by arrow e correspondingly the reflected energy is captured by the geophone c and d on the receiver r 2 and is subsequently recorded as traces in a data set the traces detected and recorded by the geophone c is illustrated as trec and the reflected energy as detected and recorded by the geophone d is indicated in the diagram as tred the subscripts trec and red refer to the corresponding traces of the geophones c and d when the seismic energy source 200 is operated in the mode as indicated by arrow e however a receiver r 3 is positioned in a non parallel and non perpendicular orientation from the seismic energy source 200 with respect to the seismic energy source 39 s 200 modes of operation the receiver r 3 comprises a geophone e and a geophone f the reflected energies are captured by the geophones e.
