Title: Photo-electric rangefinder
Inventor: PRADEL GEORGE
IPC: G01C3/04
Filed: 1967-11-07
Abstract: 1,200,778. Surveying apparatus. CARL ZEISS JENA VEB. Nov.7, 1967, No.50516/67. Heading G1F. A photo-electric rangefinder comprises an optical system 3, 6 for transmitting an intensity modulated light beam and an optical system 1, 2, 6 for receiving the beam, the two systems being mounted for joint rotation about a horizontal axis X-X and a vertical axis Y-Y. The receiving system co-operates with optical elements 16, 10, 11, 12 to form a sighting telescope. A source of light 5 is positioned at the centre of the mirror 3 and the beam reflected from a remote reflector is focussed on a sighting mark 9. The mirror 16 enables the mark 9 to be viewed in the eyepiece 10-12. For measuring the rotation of the instrument about the axis X-X a graduated scale 17 is provided and is rigidly connected to both optical systems, whilst rotation about the axis Y-Y is measured using a fixed graduated scale 18. The scales 17, 18 are illuminated by light directed on to them by mirrors 19, 30 and prism arrangements. The images of the illuminated portions of the scales are focussed on a disc 28 bearing an index mark which is viewed by an eyepiece 29 and a mirror 36, a given rotation of the eyepiece about the axis X-X causing the mirror to rotate half the given rotation. The required horizontal and vertical angles are determined by the positions of the index mark in the images of the illuminated portions of the scales. The range is determined by transmitting the intensity modulated light reflected from the remote reflector to a photoelectric receiver 15 by means of which the phase of the incident light and therefore the range are determined.

A servomotor comprises diaphragms 30, 38 arranged in tandem and carrying wall members 20, 22 respectively, wall member 20 being provided with a threaded tubular boss that is received in a threaded bore 60 in wall member 22. A partition 54 sealingly surrounds and supports the boss and carries an annular rim 26 that interconnects the peripheries of the diaphragms. Four chambers 50, 58, 56, 52 are defined and, when the control valve 80, 90 is in the released position shown, a vacuum applied to chamber 50 via a check valve 112 is communicated to the other chambers via passages 62, 64, 114, 124; the spaces between raised bosses 108 on diaphragm 38 and passage 128. Movement of the control rod 76 to the left first seats valve member 90 on seat 122 and then unseats valve member 80 from its seat on member 90, thereby communicating chambers 52, 58 with atmosphere via filters 130 and actuating the servomotor.

If the vacuum is lost, the movement of the control rod is communicated directly to walls 20, 22 via shoulder 84 on member 80 and shoulder 132 on the tubular boss of wall member 20.
