ABSTRACT:
This invention pertains to an electro-optical digital precision micrometer and gages wherein a precision scale is carried in a frame and is moved with the movable anvil portion of the apparatus. The precision glass scale has a determined number of lines engraved thereupon and as the movable anvil is moved the lines are caused to be passed in front of a grating. A light source feeds a beam of light through the scale to a reading device whereby electrical pulses are converted into signals which are fed to a digital readout. A dash pot system is provided to restrict the speed of movements of the movable and the supported glass scale so that the lines of the scale as they cut the beam of light passing through the scales are positively detected by the photosensor. In addition to using this system in a micrometer, one or more of these systems may be used in a height gage and in a linear digital gage. In all embodiments the linear motion of the movable anvil or member is converted into electrical pulse signals in such a way that both the displacement and the direction of motion can be displayed.
