Paper Abstract

This paper discusses the remote sensing based on a GaAs diode laser with an external dispersive cavity (DL EDC). The scheme provides continuous generation on a single longitudinal mode of external cavity and the generation line-width less than 1 kHz or generation on a broad mode of internal laser cavity. This source of coherent radiation provided the work of fiber-optic accelerometer, which also is fiber-optic sensor of gravity field. The fiber-optic gravimeter includes fiber-optic interferometers of Mach- Zhender and has possibility to measure value and direction of gravity field's vector in three-dimensional space. Resolution of phase shift on level 10E-3 rad gives the possibility to measure the change of value of gravity field's vector on level 10E-6*g (where g - acceleration of free fall).
