Abstract: When a piezoelectric element 3 applies an external force to a plastic photonic crystal, the photonic crystal deforms, and accordingly, the photonic band gap easily changes. When the photonic band gap changes, transmission of light with a specific wavelength is limited. Therefore, light with a desired wavelength is outputted from the photonic crystal 2 upon sufficient tuning, and extracted to the outside through an output window 6. In the present invention, a plastic photonic crystal 2 which can achieve sufficient wavelength tuning although it is small is used, and elements are unitized, so that the entire wavelength tunable light source unit is downsized.

Abstract: A photonic crystal 2 with plasticity is arranged by making microspheres of silica or barium titanate or air bubbles be contained in a gel substance. When an external force is applied to this photonic crystal, photonic crystal 2 deforms and the photonic band gap is readily changed thereby. When the photonic band gap changes, the passage of light of a specific wavelength is restricted. Light of a desired wavelength is thus output from photonic crystal 2. With this invention, this wavelength can be varied readily by means of an external force.

Abstract: An image reconstructing apparatus wherein the object under examination is irradiated in at least one direction to provide projection data, and the provided projection data is optically processed to form a reconstructed image representing the internal information of the object. An image associated with the projection data is formed and stored in the storage medium. The stored image is optically read out of the storage medium. The read out stored image which corresponds to one direction of irradiation is integrated at a time to produce sum data. The sum data and projection data corresponding to the same direction of irradiation are compared to form correction data. An image associated with the correction data is formed and optically superposed on the stored image in the storage medium corresponding to the same direction of irradiation, to produce the reconstructed image.
