Method for measuring angles between electromagnetic waves

The method relates to a method for measuring angles between electromagnetic waves which are of different colour or are differently polarized (e.g. light beams L1, L2). The incident light is focused onto a light chopper ZH by a lens K1. The chopped light is separated into two components A1, A2. Each component can be uniquely assigned to one of the two incident light beams (bundles) L1, L2. These components are received by one optoelectronic component D1, D2 each and are processed further in an electronic way. The angle of incidence beta between the light beams is expressed in a time shift of the electric signals with the aid of which it is possible to calculate the angle beta given a known speed of the light-chopping elements at the modulation site. This measuring method is distinguished by extreme sensitivity (typically 10 -5 degrees) and a very high measuring speed (several thousand measurements per second). Stochastic errors can therefore be averaged out in a short time. Reference measurements ...
