Transillumination Survey Written by Todd Bowers Last update (4-20-05) Explanation of Transillumination Survey taken from Pulse Ekko manual page 63. For a transillumination survey the transmitter and receiving antennas are placeed at opposite sides of a structure to study the trramission properties of the dividing material. Depending on the structure shape, it is desirable to obtain as many different raypaths through the structure aspossible. This is done by varying the transmitter and receiver geometry around the structure. Selection of Operating Frequency |
