Document Type and Number:
WIPO Patent Application WO/2023/135994
Kind Code:
A1
Abstract:
A shape-changeable mirror (10) comprises: a reflecting mirror (11) that has a reflecting surface for reflecting light; a first support member (21) that has a first plate part and a first securing member and supports the reflecting mirror; a second support member (31) that has a second plate part and a second securing member and supports the reflecting mirror; and an adjustment member that changes the distance between the first plate part and the second plate part. The first plate part is disposed with a defined space from the back surface of the reflecting mirror. The first securing member is connected to the first plate part, and when m is an integer of 2 or more, secures the reflecting mirror at m first securing positions of the reflecting mirror. The second plate part is disposed with a defined space from the back surface of the reflecting mirror with the first plate part interposed therebetween. The second securing member is connected to the second plate part, and when n is an integer of 2 or more, secures the reflecting mirror at n second securing positions different from the first securing positions of the reflecting mirror. The reflecting mirror has, on the back surface thereof, projections (14x, 14y) that come into contact with the first securing member and/or the second securing member.
