Installing the Hoist

The Fiber Optic Michelson-Morley sensor is two “arms”, or straight lengths, of optical fiber. These will each be 14' long and set perpendicular to one another in a horizontal plane. These arms will rotate as a unit in the horizontal plane when operating.

The purpose of the hoist is to lower the interferometer for maintenance (and initially, construction) at floor level and raise it to the ceiling for collecting data. This has the side-benefit of clearing the the floor area for general use while collecting data, which will be almost all of the time.
Installing the hoist in the lab. The hoist installed and ready for action.
This marks the beginning of construction of the FOMMX apparatus.

The next item to be constructed will be the servo motor assembly. This will attach between two I-Joists below the hoist. The hoist will lift the assembly (and the interferometer) up and lower it down.

Initially, I will have to use a ladder to lock the motor assembly in its operating position or rele…

On Mechanical Structure of FOMMX

The apparatus of a Michelson-Morley experiment measures the difference in the speed of light in two perpendicular directions and repeats this measurement over a variety of orientations. These results are combined to show the velocity of a (6D) continuum (previously 3D called aether) through the solar system.

The general approach is to direct light along two perpendicular arms and interferometrically measure the difference in speeds between the light-paths in the arms. The arms are horizontal and rotate about a vertical axis a few times a minute. The horizontal plane of rotation sweeps through a large portion of the sky each day. These rotations provide the variety of orientations needed for calculations.

The sense element of the arms is an optical fiber which lies in a tray, which in turn lies in a clear plexiglass tube 3 inches diameter. The straight length, end to end, of the fiber is about 16 feet, a bit longer than the straight light path of Dayton Miller's apparatus. One arm …

Component Cost for Experimental Apparatus (3/2/18)

Based on some theoretical work, I have identified an experiment where setting experimental parameters can cause results to either support or refute Special Relativity.

The experiment is called a Fiber-Optic Michelson-Morley Experiment or FOMMX. Its status is that I have just completed a detailed design of the apparatus, not yet fully documented. This was a grueling quick-study of diode lasers and optical fiber as applied to commercial products for laboratories. The analysis includes detailed component costs to set up the apparatus and begin collecting data and is estimated at $7,317.15. Plus or minus. Probably plus.

Next up for me on FOMMX is finishing the drawings for the 3D printed components and the mechanical assembly. David Ostby has already started on these.

This post is the first in a new series. I will use this log to record plans and progress on FOMMX.
