Laser interference method for spatial angle orientation measurements

A new method of object orientation measurement supposed. The method is based on circular interference fringes analysis with Fourier-methods and correlation analysis methods. The main element of interference sensor is aluminizing meniscus lens illuminated with laser source. Measurement system prototype was designed. Experimental results correspond to model estimation of high precision angle measurements.
