The scanning electron microscope forms images of the surfaces of objects located in a vacuum specimen chamber. A fine beam of electrons scans the surface in synchronism with a cathode ray tube whose spot brightness is modulated by the secondary electron signal emanating from the specimen. The system is capable of giving a large depth of focus and thus allows different projections of the specimen to be photographed by tilting the specimen between successive exposures. From a knowledge of the geometry of the projection (which is central or perspective, but may be justifiably treated as a parallel or orthogonal case for high magnification images), it is therefore possible to proceed to three dimensional analyses from the measurement of parallaxes. Part I of this paper deals with the practical problems resulting from mechanical design limitations of specimen stages and plotting instruments, as well as the nature and sources of image distortions. Part II deals with the practical features of the successful plotting instruments designed especially for the solution of a standardised scanning electron microscope problem in which the magnification of the two members of a stereoscopic pair of images is held constant, the angle of divergence of the peripheral “rays” of the projection from the central “ray” is assumed to be negligible (which is the case for high magnification images) and the tilt angle difference between the two specimen attitudes is constant.

Aerial reconnaissance and photography for archaeological purposes require repetition over an infinite period of time. The recognition of subsurface disturbances is dependent on soil colours or abnormal crop growth, and climatic conditions are an important factor.

Flight tests have been conducted at an altitude of 7000 m to record the environmental conditions of a metric camera on a typical survey sortie. The tests show that a larger total temperature difference of the image forming system is present when an aircraft camera window is used than when the sortie is made without a window. It is concuded that at 7000 m and greater altitudes, the metric camera will be in a thermally dynamic situation throughout the sortie unless that sortie is of considerable duration. In pressurised aircraft, the use of a thick camera window is mandatory, but there is some evidence to suggest that in non-pressurised aircraft it is better not to use a window.

Stereophotography with a pair of 35 mm cameras and stroboscopic illumination was used to record, reconstruct and measure the trajectories of falling hailstones under extremely adverse natural conditions. Since it was not possible either to fix or to measure precisely the camera positions and orientations, a method was devised to obtain both the three dimensional hailstone co-ordinates and the camera positions and orientations by making use of the otherwise redundant information contained in the stereo-photography. Resume On a utilise deux cameras de 35 mm et un eclairage stroboscopique pour enregistrer en vue de leurs restitutions les trajectoires de grelons; ceci n'a pu etre realise que dans des conditions difficiles.

Two complementary measuring instruments are described which use a very simple principle and which take three dimensional measurements or plots directly from small objects. The first instrument can achieve accuracies of ± 0·3 mm on objects whose largest dimension is 300 mm. The second can achieve ± 0·02 mm on objects smaller than a 25 mm cube. Resume On presente deux instruments de mesure complementaires el de principe tres simple permettant de relever dans l'espace des coordonnees sur de petits objets, le premier avec une exactitude de ± 0.3 mm sur des objets de dimension inferieure a 300 mm, le second avec une exactitude de ± 0.02 mm sur des objets de dimension inferieure a 25 mm. Zusammenfassung Beschreibung von zwei Zusatzmessgeraten, die auf einem sehr einfachen Prinzip beruhen und mit denen dreidimensionale Messungen oder Auswertungen von kleinen Objekten direkt durchgefuhrt werden konnen. Mil dem ersten Gerat kann eine Genauigkeit von ± 0,3 mm bei maximalen Objekt abmessungen von 300 mm und mit dem zweiten von ± 0,02 mm bein Objekten, die kleiner als ein 25 mm-Kubus sind, erreicht werden.
