TL;DR: In this article, the authors describe the detailed design of the KAGRA interferometer as well as the reasoning behind the design choices, including the length and alignment sensing schemes for the robust control of the inter-ferometer.
Abstract: KAGRA is a cryogenic interferometric gravitational-wave detector being constructed at the underground
site of Kamioka mine in Gifu prefecture, Japan. We performed an optimization of the interferomter
design, to achieve the best sensitivity and a stable operation, with boundary conditions of classical
noises and under various practical constraints, such as the size of the tunnel or the mirror cooling capacity.
Length and alignment sensing schemes for the robust control of the interferometer are developed. In this
paper, we describe the detailed design of the KAGRA interferometer as well as the reasoning behind
design choices.

Abstract: Summary A new type of interferometer for measuring the diameter of discrete radio sources is described and its mathematical theory is given. The principle of the instrument is based upon the correlation between the rectified outputs of two independent receivers at each end of a baseline, and it is shown that the cross-correlation coefficient between these outputs is proportional to the square of the amplitude of the Fourier transform of the intensity distribution across the source. The analysis shows that it should be possible to operate the new instrument with extremely long baselines and that it should be almost unaffected by ionospheric irregularities.

TL;DR: In this paper, a quasithermal, quasmonochromatic lamp is described which serves as a highly degenerate light source with adjustable coherence time between 10−5 sec and 1 sec.
Abstract: A quasithermal, quasmonochromatic lamp is described which serves as a highly degenerate light source with adjustable coherence time between 10−5 sec and 1 sec. This lamp is used for several demonstration experiments concerning the relations between coherence and fluctuations: The intensity interferometer of Hanbury Brown and Twiss is applied to measure the correlations between intensity fluctuations. The double slit experiment of Young serves to stress the role of fluctuations for classical interferometry. Interference patterns from two independent quasithermal lamps are presented.

TL;DR: In this article, a new type of dynamic measurement system that is comprised of a micropolarizer array and can work with any type polarization interferometer to measure a variety of physical properties is presented.
Abstract: We have demonstrated a new type of dynamic measurement system that is comprised of a micropolarizer array and can work with any type polarization interferometer to measure a variety of physical properties. The unique configuration overcomes many of the limitations of previous single frame, phase-shift interferometer techniques. In particular it has a true common path arrangement, is extremely compact, and is achromatic over a very wide range. We demonstrated high quality measurement with both a Twyman-Green and Fizeau type interferometer. The technique is useful for many applications where vibration or motion is intrinsic to the process.
