ABSTRACT:
An optical binary signal geophone is described. The geophone utilizes an optical fiber for the transmission of light to the geophone. The geophone contains a light chopping means which oscillates in response to vibrations imparted into a geologic formation. As the chopping means such as a baffle or a tubular member vibrates, it chops the light signal and creates an on/off light pattern. The light passing through a slit in the baffle or tubular member is returned to the seismic vehicle for further processing. The optical geophone creates a binary signal directly without the use of clipping electronics and magnets or coils used in conventional geophones.
