摘要： PROBLEM TO BE SOLVED: To provide a projector that prevents light rays from being incident on a projection optical system at unnecessary angles to suppress heating of the projection optical system and focus shift.SOLUTION: The dimming mechanism drive part 93 of a control unit 90 changes the open/close state of the dimming mechanism 80 in accordance with the F number of the projection optical system 70. This operation allows illumination light having the angular distribution corresponding to the F number of the projection system 70 to be incident on the projection system 70 and prevents the illumination light from being blocked by a lens barrel, a diaphragm, or any other similar component in the projection optical system 70. The light blockage prevents the projection optical system 70 from being heated unnecessarily, focus shift of the lens in the projection optical system 70 is prevented and fuzziness is eliminated without changing the luminance of the illuminator 10 itself.

摘要： PROBLEM TO BE SOLVED: To provide a projector for improving contrast of a liquid crystal panel by adjusting illuminating direction.
SOLUTION: Distances D1 and D1' from the center point O of a second lens array 21e to the outer circumference in a first characteristic up, down, right, and left directions are larger than a distance D2 from the center point O of a second lens array 21e to the outer circumference in a second characteristic direction tilted at an angle of 45°. Therefore, as for the high contrast direction of a first liquid crystal panel 25a, an illumination light can be made incident on the first liquid crystal panel 25a at a comparatively large incident angle, and as for the low contrast direction of the first liquid crystal panel 25a, an illumination light can be made incident on the first liquid crystal panel 25a at a comparatively small incident angle. Thereby, the contrast of an image projected by a projection lens 29 on a screen can be improved as a whole.

摘要： PROBLEM TO BE SOLVED: To provide a projector increasing the F-number of an illumination optical system, without enlarging the illumination optical system, etc. SOLUTION: A coupling lens 43a cooperating with a superimposed lens 35 is provided only in a first section between a first dichroic mirror 41a and a reflecting mirror for red 42a being a bending mirror, in a first optical path OP1 from the superimposed lens 35 to a first liquid crystal display panel 61r. Thus, the F-number of the illumination optical system 30 for blue can be adjusted with a high degree of freedom and the increase in the number of lenses constituting a color separation light guide optical system 40 and the illumination optical system 30 can be prevented. Furthermore, illumination light can be prevented from entering with a large incident angle around the first liquid crystal display panel 61r and the telecentric properties of the illumination optical system 30 for blue can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a projector where more accurate correction of chromatic aberration is performed, thereby restraining the occurrence of irregularity and blurring in an image, and making high efficiency of using light. SOLUTION: The incident surface of a first dichroic mirror 31 is arranged at an angle larger than 45° by a very small angle with respect to an illumination optical axis OA so that the reflection angle of R light on the first dichroic mirror 31 may be smaller than 45° by the very small angle, that is, a bending angle α in the optical axis direction of a first optical path OP1 may be smaller than 90°. Thus, the length of the first optical path OP1 is made somewhat longer than the length of the second optical path OP2, and the correction more corresponding to the chromatic aberration is performed than in the conventional projector.

摘要： PROBLEM TO BE SOLVED: To propose a novel approach for acquiring a temporally decomposed waveform of scattering light with a high resolution, and to propose an approach for measuring the concentration of a component contained in an examinee with high accuracy.SOLUTION: Light-source beams from a light source 301 are split by a splitter 302, and an examinee is irradiated with one of the light beams as measuring light by an irradiator 303. Light emitted from the examinee is converged by a convergence section 304 and relayed to an optical converter 307 by a relay 305. On the other hand, the other beam split by the splitter 302 is guided to an optically driven shutter 311 as gate light. In this event, an optical path length of the gate light is changed by a gate light guide 309 and gate light of a different optical path length is guided to a Kerr substance 311A. Then, a temporally decomposed waveform is determined from the result of detecting the intensity of light in the changed optical path length, and the concentration of a component contained in the examinee is calculated.
