Visible interferometry at µarc-second accuracy requires measurement of the interferometric baseline length and orientation at picometer accuracy. The optical metrology instruments required for these interferometers must achieve accuracy on order of

Liquids have not found widespread application in optical design for a number of reasons, one of which is the fact that index of refraction data for liquids is available for only very few compounds, and the data that do exist are only in the visible s

Abnormal dispersion is found in a large number of optical liquids. These liquids are quite useful in the design of apochromatic lens systems because they are inexpensive and are readily available compared to the expensive abnormal dispersion glasses

It has been demonstrated recently that high performance apochromatic lenses and objectives can bedesigned using optical liquids that have abnormal dispersion properties. This has opened the way to lowcost apochromatic objectives with optical quality

Interferometry has long been used to visualize the gas density distribution that results from aerodynamic phenomena. This paper describes an interferometer system that produces quantitative data. The resulting phase maps are high resolution and high

The cross-sections of high-speed aerodynamic phenomena are presently measured by means of a system that interferometrically ascertains optical path length changes with high spatial resolution. Attention is given to the optical disturbance through an

The predictions of a model presented previously are tested with data on five styrenebutadiene–styrene copolymers. Differential scanning calorimetry and laser light transmission are the primary tools, spanning 180–630°K, with some evidence suppli

A microstructural model for the phase-separated states of ABA triblock copolymers is proposed. It postulates the simultaneous existence of three phases: pure A, pure B, and a mixed region. Incorporation of the mixed region distinguishes this treatmen
