Title:
POLARIZED LIGHT IRRADIATION DEVICE AND POLARIZED LIGHT IRRADIATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/068960
Kind Code:
A1
Abstract:
In order to make a polarized light irradiation device more compact and in particular to shorten the longitudinal length thereof, a stage, on which a target is placed, a polarized light irradiation unit, which irradiates approximately band-shape polarized light in a direction approximately perpendicular to the scan direction of the target, and an optical measuring instrument, which measures properties of light irradiated from the polarized light irradiation unit, are disposed such that the horizontal positions thereof do not overlap when the polarized light irradiation unit is in a standby position. A light source moving unit moves the polarized light irradiation unit in the scan direction of the target so that the polarized light irradiation unit passes above the optical measurement unit or above the stage.
