    • [PROBLEMS] To provide a shape measuring apparatus having a configuration which enables the operation for aligning a measuring probe and a candidate object to be simplified when the shape of the candidate object is measured.[MEANS TO SOLVE THE PROBLEMS] A shape measuring apparatus is configured so that an optical probe 20 moves relative to a candidate object, and the three-dimensional shape of the candidate object is measured without contact from information obtained by the optical probe 20. The shape measuring apparatus includes a gantry structure 10 allowing the optical probe 20 to be moved to a predetermined position relative to the candidate object, and a support device 30 allowing the candidate object to be rotated around at least two rotational axes.

    • Information light modulated and emitted by a modulation element is led to a recording medium through a Fourier transform optical system and an optical path shifter. An interference image is recorded on the recording medium by interference of the information light and reference light. A deflection unit of the optical path shifter has a pair of prisms. Optical path of information light transmitted through the respective prisms are shifted in parallel in a direction perpendicular to an optical axis of the Fourier transform optical system. By rotating the deflection unit around the optical axis, it is possible to shift the optical path of the information light around the optical axis while shifting the optical path in the direction perpendicular to the optical axis. Therefore, it is unnecessary to perform complicated control and it is possible to multiply record an interference image accurately with an information recording apparatus having a simple structure.
    • 通过傅里叶变换光学系统和光路移动器将由调制元件调制和发射的信息引导到记录介质。 通过信息光和参考光的干涉将干涉图像记录在记录介质上。 光路移动器的偏转单元具有一对棱镜。 透过各棱镜的信息光的光路在与傅立叶变换光学系统的光轴垂直的方向上平行移动。 通过围绕光轴旋转偏转单元,可以在沿着与光轴垂直的方向移动光路的同时沿光轴移动信息光的光路。 因此,不需要执行复杂的控制,并且可以与具有简单结构的信息记录装置准确地将干涉图像记录下来。
