MIRROR SEISMOGRAPH Russian patent published in 2022 - IPC G01V1/18 

FIELD: measuring technology.

SUBSTANCE: invention relates to devices for recording ground vibrations generated by seismic waves from natural and artificial sources (earthquakes, volcanic eruptions, explosions, man-made disasters, etc.). Essence: the device contains a housing (1), an inert mass (2), three parallel mirrors (3, 4, 7). The central mirror (7) is located between mirrors (3, 4) and bonded to an inert mass (2). Two lasers (5, 6) are positioned at an angle to the mirrors (3, 4) on the side of the central mirror (7) attachment to the inert mass (2). On the opposite side from the lasers (5, 6), two lines (9, 10) of photosensitive elements are installed, made with the possibility of registering the signal in digital form. In this case, the central mirror (7) is made in the form of a substrate with reflective coatings on both sides.

EFFECT: improving the accuracy of measuring ground vibrations, digital registration of ground vibrations.
