Abstract

895,600. Photo-electric movement detectors, PERKIN-ELMER CORPORATION. Nov. 10, 1958 [Nov. 13, 1957], No. 35960/58. Class 40(7). Movement of a body, e.g. the swayings and twistings of structures e.g. tall buildings and bridges, or the movements of gyroscopically stabilized platforms, is detected by reflecting two beams of light of different colour or differently modulated on to a radiation sensitive device which indicates the relation between the intensity of the beams. In the arrangement shown in Fig. 9 light from arc lamp 20 is focused in a slit 23 and an image of the slit is formed on a mirror 26 via a mirror arrangement 25 or a pentaprism. Two chopping discs 22 interrupt the halves of the beam in antiphase and rotation of mirror 26 causes the relative quantities of the two components of light incident on a photo-cell 28 to vary the difference is defected by a phasesensitive detector 31 fed with a voltage synchronized with the chopping plates and the output is fed to a servomotor 32 which rotates the cell housing until the amount of each beam falling on the cell is equal. In addition, a triple mirror reflects light back through the mirror arrangement to a further photo-cell 29 which similarly controls a servomotor 34 to adjust a plate 30 carrying mirror 25 and the anguiar deflection detecting arrangement sideways until the two light components incident on cell 29 are equal. The translational movement of the plate indicates the translational movement of the body and the angular movement of cell 28 indicates the rotational movement.
