Abstract
The present invention proposes a torsion balance apparatus with high sensitivity and accuracy to measure extremely small rotation angle. The torsion balance apparatus comprises a bar which rotates and is horizontally suspended by a suspending fiber, a light source, a detector and a light reflecting system which reflects the light beam from the light source several times and reaches to the detector.
