Abstract:

An inclinometer which employs a light and the laws of optics for measuring the tilt angle from the local horizontal. The local horizontal is established by using a low viscosity reflecting liquid. An interferometer sums two light beams at a predetermined point and the resulting interference finge pattern is detected by a detector. The fringe pattern changes as the test table changes pitch angles. Author
