Abstract
A deformable mirror includes a deformable section in which, a reflecting surface is formed, a fixing section which fixes an outer periphery of the deformable section, a GND electrode which is formed on the deformable section, a drive electrode which is provided facing the GND electrode, and a driving-signal source which deforms the deformable section by an electric voltage applied between the GND electrode and the drive electrode. The deformable mirror is sealed such that a pressure inside to be lower than an atmospheric pressure, and is provided with a capacitance detecting circuit which detects a change in response characteristics of the deformable section associated with a pressure change of a sealed-inside.
