  • Patent number: 11346647
    Abstract: A shape measurement device includes a stylus configured to contact an object to be measured; a measurement arm that supports the stylus to allow the stylus to contact the object to be measured; a measurement arm part that supports the measurement arm; and a measurement arm support that supports the measurement arm part to allow the stylus to move along an outer shape of the object to be measured. The measurement arm support includes a support body provided with a movement rail formed on a top surface thereof. A body coupling block is coupled to the movement rail to move along the movement rail and is detachably coupled to the measurement arm part. The measurement arm portion includes a body provided with a block accommodation groove to accommodate the body coupling block and a position-fixing member coupled to a lower surface of the body defining the block accommodation groove.

  • Patent number: 9864190
    Abstract: Aspects of the present invention are directed to apparatuses, arrangements, systems and methods for collecting information using one or more modalities. As consistent with one or more embodiments, an apparatus includes first and second scanning mirror arrangements having different scanning axes and respectively facing different directions. The first scanning mirror arrangement directs source light and image light in two paths, and the second scanning mirror arrangement directs image light from a target to the first scanning mirror arrangement. The first and second scanning mirror arrangements cooperatively scan source light from the first scanning mirror and via the second scanning mirror to target locations with at least two degrees of freedom, and direct image light from the target locations.
