Title:
MEASURING DEVICE, MEASURING SYSTEM, MOVING BODY, AND MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/189429
Kind Code:
A1
Abstract:
A measuring device which measures an inspection target on the basis of vibrations generated when the inspection target is irradiated with laser light is provided with: a condensing position deriving portion which, on the basis of the distance between a laser device for radiating laser light and a location irradiated by the laser light, derives an amount of adjustment of a distance between condensing lenses in a laser condensing unit which condenses the laser light; and a communication portion which transmits control information, including information indicating the amount of adjustment, to the laser condensing unit.
