COMPENDIUM INCLINATION MEASUREMENT
WYLER AG, WINTERTHUR / SWITZERLAND

2.5 ELECTROLYTE VIALS

Electrolyte vials are made of glass, si-
milar to precision vials, but filled with a
liquid that is an electrical conductor. By
inclining the vial, the outer portions of
the vial (electrodes) will be more or less
covered by the liquid. The electrolyte vial
will supply a voltage proportional to the
inclination. 1: Outer electrodes

2.6 TARGET LASER
The system consists of a laser sender
and a laser receiver unit. The sender unit
is a high stabilility semi-conductor laser
precisely adjustable with a mechanical
device for targetting. The receiver unit is
a 10x10 mm PSD (Position Sensing De-
tector), an opto-electronic device with
a complete amplifying and computing 1: Laser transmitter
electronic unit based on a DSP (Digital 2: Laser receiver
Signal Processor). 3: Object to be measured

2.7 LASER INTERFEROMETER
The measuring system consists of a
laser with detector, an angular interfero-
meter-reflector and a retroreflector.The
laser beam is split in the interferometer
and runs from there on in two different
paths (measuring beam and reference
beam). On the return path the two be-
ams will be superimposed to form one
beam again. The difference in path dis-
tance leads to a difference in return time
and therefore a phase difference is the 1: Laser with detector
result. This phase difference results in 2: Angular reflector
an interference that can be measured. 3: Reflector
