    Abstract: One example is a shock gauge system for measuring an external blast to a hull. The shock gauge system includes at least one accelerometer to produce acceleration data in response to the external blast, a mass with an accelerometer affixed to it, a crush block, a linear displacement potentiometer (LDP), a camera, and a processor logic. The LDP device generates displacement data of a mass being pushed into the crush block when reacting to the external blast. The camera captures images of movement of the mass. The processor logic verifies if the acceleration data is valid by correlating the acceleration data to the displacement data, the images, and/or an amount of displacement into the crush block by the mass. When the acceleration data is valid, the acceleration data may be used to create a more blast resistant hull.

    Abstract: An optical beam splitter has an imaging lens assembly with a single optical axis and reflectors located on the image side of the lens to produce a number of real images of an object imaged by the lens. The imaging lens assembly is designed to image the real image formed by a camera lens assembly on the optical axis where the camera lens assembly has an exit pupil a known distance on the object side of this real image. The imaging lens assembly is then adapted to image this exit pupil of the camera lens to an aperture plane adjacent the reflectors. The optical beam splitter is described in particular in an application in an electronic high speed camera wherein multiple images of an object are formed for high speed photography.

    Abstract: A three-dimensional photographic system includes a source of pulsed-optical radiation characterized by an output optical pulse of risetime length less than the depth resolution desired of an object to be photographed. The pulse is directed on the object; the reflected radiation from the object is collected by an array of optical lenslets (lenticular plate), which forms a corresponding array of images of the object. This array of images is streaked, for example, by a streaking image converter tube, to form a corresponding array of streaked images in accordance with the said array of images of the object as a function of time. The array of streaked images is then recorded by a photographic film camera on other recording means; the recorded film can then be analyzed or viewed with human eyes for the purpose of three-dimensional analysis or viewing of the object. Particularly one optical pulse enables a recording which can subsequently be unscrambled to yield a three-dimensional image for measurement or for binocular viewing even though the distance of the object for the viewing point is much too great for normal binocular stereoscopic perception of depth.

    Abstract: A method and apparatus for optically recording dual images of the same body wherein a first image is reflected directly into a camera through a light discriminating filter, and a second image of the body is reflected into the camera through an optical path defined by an arrangement of reflective surfaces having a second light discriminating filter in the path such that the two images may be discriminated after recording.

    Abstract: An optical shutter-camera includes a first optical unit, a deflecting unit, and a second optical unit. The first optical unit receives image rays from a subject and outputs first optical image rays to form a first optical image of the subject. The deflecting unit includes a deflection member and a pumping unit. The deflection member is a nonlinear optical material whose refractive index is varied by beam radiation. The pumping unit radiates a pumping beam having a variable intensity to a required region of the deflection member and varies the refractive index of the required region to variably deflect optical paths of the first optical image rays. The deflection unit is positioned so that a deflection center of the optical paths of the first optical image rays, formed when the variable intensity-pumping beam in incident on the deflection member, substantially agree with a position where the first optical image is formed. The second optical unit receives the first optical image rays from the deflection unit and outputs second optical image rays to form a second optical image of the subject. The second optical unit includes an aperture. The aperture restricts one of the first optical image rays and the second optical image rays.
