6D40.25 Demonstrate an interferometer using chicken wire mirrors and a 12 cm microwave. Ol-20 Make a microwave Michelson interferometer with window screen reflectors and a chicken wire half reflector. The two mirrors are adjustable about mutually perpendicular axes. 6D40.30 Jamin interferometer 35-2.9 Use second surface mirrors at and angle generate parallel beams in this interferometer. Real fringes are observed with the Sagnac interferometer with both a point source and an extended source.
Virtual fringes require an extended source.
Also applies to Michelson interferometer. The triangular interferometer is explained. Diagrams, Construction details in appendix, p. 1353. Also transverse coherence. A long path interferometer uses corner reflectors instead of mirrors and the output beam is directed onto a photodetector feeding an audio oscillator.
