This paper proposes a novel alignment system based on the measurement of optical path using a light beam scanning mode in a transmissometer. The system controls both the probe beam and the receivin...

An automatic alignment system for measuring optical path of transmissometer based on light beam scanning

This article describes two methods for measuring the tilt of defective surfaces in a multi-element lens.

Measurement of the tilt of defective surfaces in a multi-element lens

This paper deals with a new method of the alignment of planes and straight lines. Reflecting systems are used, giving double-ray bundles with mirror symmetry.
