Title:
OPTICAL ASSEMBLY FOR THREE-DIMENSIONAL MEASUREMENT DEVICE AND THREE-DIMENSIONAL MEASUREMENT DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2021/044960
Kind Code:
A1
Abstract:
An optical assembly (13) for a three-dimensional measurement device is equipped with: an optical lens (320) that forms a pair of conjugate planes having an optically conjugate relationship; an optical device (341) that is disposed on one of the pair of conjugate planes; a temperature sensor (354) for detecting the temperature of the optical lens (320); a heater (350) for heating the optical lens (320); and a control unit that controls the operation of the heater (350) on the basis of the result of the detection made by the temperature sensor (354) such that the optical lens (320) reaches a given temperature.
