Abstract: An image pickup device, wherein a luminous flux LF having passed an aperture (5) in one direction is detected by a detection unit 9, and a locating luminous flux LB having passed the aperture (5) in the opposite direction is introduced into a position (x, y) of a first optical image IM1, as corresponding to a specific position (x, y) of a second optical image IM2, on an image pickup plane. Independently of the mechanical error at the moving time of the aperture (5), therefore, the detection result of the luminous flux LF detected by the detection unit (9) indicates the data of the specific position, as indicated by the locating luminous flux LB, of the incoming optical image.

Abstract: PROBLEM TO BE SOLVED: To provide a laser light irradiation apparatus which can maintain the diameter of condensing spot of a laser light small even when the wave front shape of the laser light varies in the middle of laser light irradiation. SOLUTION: A laser light irradiation apparatus 1 includes a laser light generating portion 10, a wave front shape adjusting portion 20, a branch portion 30, a light condensing portion 40, a wave front shape acquiring portion 50, a control portion 61, a point light source 70, and a reflecting mirror 80. The wave front shape of a reference laser light L S output from the point source 70 and passed through the light condensing portion 40 is acquired by the wave front shape acquiring portion 50. The wave front shape of a second laser light L 2 of a laser light L 0 output from the laser light generating portion 10 and branched into two by the branch portion 30 is acquired by the wave front shape acquiring portion 50. An added distortion given to the laser light L 0 at the time of reflection in the wave front shape adjusting portion 20 is controlled so that the irregularity of the wave front shape of the second laser light L 2 is inverted to the wave front shape of the reference laser light L S , thus the wave front shape of the laser light L 0 after the reflection is adjusted.

Abstract: PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which a nonlinear optical effect generated in a substance can be measured directly. SOLUTION: Optical pulses from an ultrashort-pulse light source 11 are branched by an optical branching device 12 so as to be guided to a medium 4 to be measured, as exciting pulses and probe pulses having a prescribed linearly polarized state by an excitation optical system 2 and a probe optical system 3. An interaction region which is generated in the medium 4 when the exciting pulses are incident and in which a refractive index is changed due to a nonlinear optical effect, is irradiated with the probe pulses. The component, out of the component which is passed through the medium 4, of the probe pulses which are passed through the interaction region and whose polarization state is changed, is detected by a camera 53 via an analyzer 51 in a light detection part 5. As a result, the nonlinear optical response of the medium 4 can be measured.
