    Abstract: DEPTH OF RANGE INFORMATION IS EXTRACTED BY PROJECTING THE IMAGE OF A ZONE PLATE UPON A SCREEN AND PHOTOGRAPHING THE SCENE AT A DIFFERENT ANGLE FROM THE ZONE PLATE SOURCE. A TRANSPARENCY OF THE PHOTOGRAPH INCLUDING ZONE PLATE MODULATION OF THE SCENE FORMED ON PLANES IN THE SCENE IS THEN FILTERED BY A SCANNING SLIT AT THE ZONE PLATE FOCAL PLANE AND PRESENTED UPON AN OUTPUT SCREEN FROM END TO END, AS A FUNCTION OF ORIGINAL RANGE, FROM THE ZONE PLATE. THE REFLECTION OF THE IMAGE UPON THE SCREEN IN VIEWED IN A VARIFOCAL MIRROR DRIVEN IN SYNCHRONISM WITH SCANNING BY THE FILTER. THE SCREEN AND THE VARIFOCAL MIRROR MAY BE CONNECTED BY A LOW-BANDWIDTH, VIDEO CHANNEL AND A CHANNEL FOR CONTROL SIGNALS FOR THE MIRROR.

    Abstract: A six degree of freedom force transducer is provided on a manipulator's hand and includes a plurality of I-beam modules having strain gauges on the flat surfaces of the thin legs of each I-beam for measuring the bending moments of each leg. According to one embodiment, a pair of strain gauges are located on each side of the leg, providing a total of four gauges in each leg. The end bells of each I-beam are adapted to be rigidly interconnected with either other I-beams, structural members of the manipulator fingers, the drive member for the manipulator, or to intermediate coupling blocks designed to rigidly interconnect I-beams. A plurality of I-beams and interconnecting blocks can be connected in various configurations to provide a determination by the strain gauges of the six components of forces and moments which are applied by forces and moments on the fingers of the manipulator system. The I-beams and interconnecting blocks are arranged in x-y-z orthogonal directions such that the structural stiffness is in the same order in different directions. The moment at each basic module can be measured by the voltage output of a bridge associated with the strain gauges. In this fashion, a determination of the position and orientation of an object in the manipulator's hand can be readily provided by a computer which solves the force and moment equilibrium equations associated with the I-beam strain gauges.

    Abstract: 1308486 Optical processing of images INTERNATIONAL BUSINESS MACHINES CORP 7 Dec 1970 [23 Dec 1969] 57955/70 Heading G2J An image processing system includes means for projecting zone plate encoded images, means positioned at the focal lengths of the zone plate encoded images for spatially filtering the projected images and means for displaying the filtered images. The coded image is formed by projecting a zone plate image on to an object and recording an image of the thus coded object. The recorded image 31 is then illuminated and forms images in the focal plane of the zone plate 16", 17" . A filter 35 is located in this plane and has a slit 36 which is caused to scan across the plane. Filtered images 18"', 19"' formed on a screen 40 are displayed by a varifocal reflector 50. The varifocal reflector 50 is synchronously operated with the slit 36. Three-dimensional features of the object, initially recorded in coded-form on a two-dimensional film, are thus displayed. In an alternative embodiment an electro-optic plate 72 is located in the coded image plane. The elemental strips of plate 72 are also synchronously operated with a varifocal reflector. A stop 33 is located at the focal plane of imaging lens 32. In a further embodiment, Fig.6, film 31 is illuminated and an image formed by lens 32 on a filter 35 having a scanning slit 36. A lens 39 sets up a filtered image on screen 40. A television camera 100 picks-up the image portions as they are formed on screen 40, displays them as a cathode ray tube 102 and the final three-dimensional display formed on variofocal reflector 50 operated synchronously with slit 36.
