摘要:A measurement apparatus having a measurement light source for emittingmeasurement light, a projection unit on which reflected light formed when themeasurement light is reflected from the mirror plane is projected as a projected light
spot, an image pickup unit for picking up an image of the projection unit on which thereflected light is projected as the projected light spot, a control unit for controlling aninclination of the mirror plane and a measurement unit for measuring a quantity ofmovement of the projected light spot, which moves according to a change of theinclination of the mirror plane, on the basis of the image of the projection unit. Thisenables the measurement of a deflection characteristic of a mirror system having themirror plane variable to arrange the inclination within a short period of time and with highaccuracy.
