Abstract: A light pulse from an ultrashort pulse light source 11 is split by a beam splitter 12 and guided, to a detection medium 4, as an excitation pulse and probe pulse having respective predetermined linearly polarized states by an excitation optical system 2 and probe optical system 3, respectively. A light track region which is generated in the detection medium 4 by incidence of the excitation pulse, and in which the refractive index is changed by a nonlinear optical effect, is irradiated with the probe pulse. Of components which have passed through the detection medium 4, a probe pulse component whose polarized state has changed through the light track region is detected by a camera 53 via an analyzer 51 in a photodetection part 5. This realizes a light track observation apparatus capable of directly observing the light track of an excitation pulse.

Abstract: In an imaging apparatus, a detection section 9 detects a beam LF having passed through an aperture 5 in a first direction and a location designation beam LB having passed through the aperture 5 in the opposite direction is made incident to a position (x,y) in a first light image IM1 on an image pickup surface corresponding to a specific position (x,y) in a second light image IM2, whereby the result of detection of the beam LF detected at the detection section 9 indicates data at a specific position in an incoming light image designated by the location designation beam LB, regardless of whether there is a mechanical error in movement of the aperture 5.

Abstract: A fluorescence component that passes through a region of a detection medium where a change in refractive index has been induced through a nonlinear optical effect produced in the detection medium by a gate pulse is observed as a fluorescence image by utilizing a change in polarization state. By observing the change in position of the fluorescence image while correlating with the change over time in the fluorescence, a fluorescence lifetime measuring apparatus is realized with which the change over time in the fluorescence, in particular the fluorescence lifetime, can be measured efficiently with high temporal resolution.

Abstract: An all optics type semiconductor image storage apparatus includes a superlative semiconductor device. The superlattice semiconductor device includes a superlattice layer which is formed by alternately laminating a barrier layer and a quantum well layer. The superlattice layer is interposed between two carrier confinement layers, one of which is formed on a surface of a semiconductor substrate. The superlattice semiconductor device has an effect of modulating a light absorbance in the vicinity of an absorption edge by canceling an internal electric field generated by a piezoelectric effect. This piezoelectric effect is due to a distortion occurring when the superlattice layer is formed. An image is stored so that, light incident into the superlattice semiconductor device at a first stable point is substantially transmitted, while light incident into the device at a second stable point is prevented from being substantially transmitted.

Abstract: Operation results for all combinations of input optical signal values to be operated are previously determined and substantially parallel light beams reflecting the operation results for all combinations are generated. Selectors for selecting transmission area of the input light beams in accordance with digital information born by optical signals are arranged for the respective optical signals along the direction of propagation of the light beams. Through the logically cascade-connected selectors, an optical signal corresponding to a combination of current input optical signals is selected from the operation results for all combinations.
