Abstract

The Laser Gravitational Field Fluctuation Detector is designed to detect gravitational fluctuations in the Earth's gravitational field as for example when the Earth is influenced by the Sun or Moon's gravitation field which results in ocean tides. This detection is accomplished by measuring the deviation of two light beams from their normal paths in reference to each other when subjected to a gravitational field, due to the fact that a perpendicular beam is affected differently than a parallel beam. Both beams having been created from a single beam by means of a narrow angle glass prism beam splitter are affected each differently by the gravitational field. Fluctuation detection is accomplished by recombining both beams by means of two mirrors and the beam splitter in order to produce a bull`s eye type of interference pattern which can be viewed through the eyepiece and also recorded through the eyepiece by a camera or photocell.

Description

Disclosure.

The principle of operation is quite simple, the laser beam first passes through the pinhole which creates a pinpoint light source and also spreads the light out to some degree. The light is then diverted into two beams by the glass prism beam splitter which prevents closely spaced unwanted double images, each beam is then reflected by a mirror and returned to the beam splitter which directs it into the eyepiece, such as from a microscope or binoculars, where it can be viewed or photographed.
The alignment is done by first removing the eyepiece, and then looking directly into the beam which is not hannful since its intensity has been reduced by the small pinhole and also further reduced by being reflected of the glass surface of the beam splitter prism, the system is then aligned. What normally is seen are two bright red dots of light in the same vicinity.
By adjusting the angles of the mirrors and the bearn splitter the two dot have to be brought to coincide so that they will appear as one dot, although the dots being sliglitly apart in any direction will also works, but this produces a different interference pattern of parallel lines perpendicular to the direction of the dots. The distance from one mirror to the beam splitter has to be slightly longer than the distance to the other mirror in order to produce the concentric rings once the eyepiece has been put back. The pattern of rings can be viewed or photographed or recorded by a computer with a computer camera.
Fluctuations in the Earth's gravitational field will show up in a manner that the rings from time to time for no apparent reason move towards the centre or away from it, as well as the entire pattern may'also shift.
Any similarities with the Michelson interferometer designed to measure the Earth's motion through space or the Twyman-Green interferometer designed to detect any unevenness in optical surfaces as well as laser holography is, except for the basic principles of light interference, purely coincidental after all our device detects fluctuations in the Earth's gravitational field which is different from the purpose of all the others which also employ the basic principle of light interference.
We believe that the magma at the centre of the Earth rotates faster than the Earth itself and al so at an angle to the Earth's axis and causes the tectonics plates floating on the molten lava to drift, the rotation also produces the Earth's magnetic fieI.d, it may be Eddies which produce gravitational fluctuations that may result from time to time into earthquakes.

Fig. 2 When the instrument is correctly positioned fluctuations in the Earth's gravitational field will cause the interference pattern rings to either drift outward or inward. Tilting the instrument will also cause a drift of the patterns. These patterns were produce by tilting the instrument in order to show a more precise pattern as can be seen that the center can vary between bright and dark while the rings around it become larger or smaller. In other words the rings originate from the center or vanish into the center.

Description of how it works.
As shown in Fig. 3 the light from the laser A is first directed to the metal plate B
with the small pinhole in it, after having passed through. it, the light is then reflected by the glass surface of the narrow angle prism C vertically downward to mirror D
from where it is reflected back upward passing through prism C into eyepiece E.
The light from laser A will also, after having passed through the pinhole in metal plate B, pass through prism C and is then reflected off mirror F and returns to prism C
from where it is reflected and also directed into eyepiece E where it combines with the other beam to form an interference pattern that can be seen with the eye or recorded with a camera as shown in Fig. 2 or with a photosensitive device to produce a graph.

Claims

1. A device for the use of measuring fluctuations in the Earth's gravitational field or others such as from the Sun or Moon in order to assist in earthquake detection, said device comprising a monochromatic light source such as from a laser, a metal plate with a small pinhole in it, a narrow glass prism as beam splitter, two regular mirrors, an eyepiece, an electronic camera and a support structure.

2. The device described in claim 1 operates on the principle that gravitational fields affect light, such as bending or distorting its regular path. Due to the fact that the beams are at different angles to the direction of the Earth's gravitational field, one being parallel and the other perpendicular in relation to it, they are affected unequally resulting in a drift in the interference pattern after they have been recombined, the pattern is similar in nature to that produced by Young's pinhole experiment.

3. The device as described in claim 1 and claim 2 is based on scientific evidence obtained by modern astronomy, such as the fact that gravitational fields from collapsed stars known as black holes distort the view of objects such as galaxies behind them by bending the light paths around them.
