摘要:
A review of the present knowledge of conventional polishing techniques is presented, concentrating particularly on the pitch polishing technique for high precision optical surfaces. This technique still depends completely on the artistry of highly skilled opticians who have a largely intuitive understanding of the process. The aim of this article is to point out that the course of surface shape development during the polishing process can be explained in terms of available technical knowledge and consequently that an improvement of polishing technique, based on this knowledge, is feasible.

摘要:
The number of elements which can be tolerated in optical systems for use in the 8 w-13 w infra-red waveband is limited to perhaps two or three. This paper shows that useful though crude zoom systems can be designed with such small numbers of elements. Several all germanium systems of varying zoom ratio are described and an evaluation of their aberrations is given.

摘要:
Television holography systems are considered with particular emphasis on the resolution requirements of the camera and reproducer. Methods are shown whereby conventional cameras and reproducers can be efficiently used at real-time scan rates. The spatial frequency requirements for the camera are minimized by using an on-axis reference wave. This wave is shifted in frequency or phase so as to create a signal that allows for the separation of the desired image terms.

摘要:
L'utilisation des cristaux biaxes pour la fabrication d'interféromètre à polarisation permet d'en modifier favorablement les propriétés. On montre que l'ouverture utilisable des faisceaux, dans le cas du prisme de Wollaston, et le domaine de linéarité des franges, dans le polariscope de Savart, sont sensiblement augmentés par le choix de certains constituants dont nous donnons les caractéristiques.

摘要:
Après avoir étudié la possibilité de sélectionner une vibration privilégiée d'un éventail de vibrations cohérentes dont les amplitudes varient en progression géométrique, une application de la méthode est décrite sur un cas particulier d'un nouveau type d'interféromètre utilisant l'effet Faraday.

摘要:
The rotating modulation collimator is so promising as an efficient astronomical x-ray camera that the data-reduction techniques merit further development. The mathematical problem is equivalent to that encountered in connection with image formation by a thin annular-aperture pupil. An unorthodox procedure based on least-squares fitting is proposed for the requisite image synthesis. The method basically seeks the best sinusoidal fit to the measured signal phases around the pupil to locate the brightest star, subtracts its contribution to that signal, and iterates.

摘要:
By representing a powdered sample as a collection of rough-surfaced spherical particles of uniform diameter, an equation was derived which relates the diffuse reflectance to the index of refraction, absorption coefficient and particle diameter. The equation, which is extremely simple in form for convenient application, is applicable for weakly absorbing powdered samples. It was tested by the use of published experimental data.
