    摘要: Provided is an observation device which can obtain a phase image of a moving object rapidly with high sensitivity even when using a photodetector having a slow read-out speed per pixel. The observation device 1 comprises a light source 10, a first modulator 20, a second modulator 30, a lens 40, a beam splitter 41, a photodetector 46, and an arithmetic unit 50. The lens 40 receives scattered light generated by a moving object 2 and forms a Fourier transform image of the object 2. The photodetector 46 outputs data representing a sum in a v direction of data temporally changing at a frequency corresponding to a Doppler shift frequency of the light having reached each position on a light-receiving surface through the lens 40 at each position in a u direction at each time. The arithmetic unit 50 obtains an image of the object 2 according to the output of the photodetector 46.

    摘要: A laser beam emitted from a laser source is projected onto a target set in a vacuum chamber while being focused by a focusing optical system. This results in generating fast particles, such as protons and emitting the particles from the target. A light measuring device measures plasma emission from the target upon in-focus irradiation with the laser beam and an analyzing device analyzes a measurement signal therefrom to assess a generation state of fast particles. Then the focusing optical system and target are controlled through optical system moving mechanism and target moving mechanism on the basis of the result of the analysis and feedback control is performed on the generation state of fast particles in the target. This realizes a fast particle generating apparatus capable of monitoring the generation state of fast particles in real time and thereby efficiently generating the fast particles.
