    摘要： An illumination apparatus providing light with a homogeneous brightness distribution, including: a light emitting unit that outputs light; a light condensing unit that condenses the light output from the light emitting unit; a diffusion unit that diffuses the light condensed by the light condensing unit; and a uniformizing optical system, such as a rod integrator or light tunnel, that receives the light diffused by the diffusion unit, uniformizes a brightness distribution thereof compared with that of the light being received, and outputs the resulting light. Applications include structured light pattern projection for 3D measurements and robot handling.

    摘要： An image projection apparatus (1) includes an illumination device (10), an optical-path forming section (21, 22, 23), an image forming element (24), a projection optical section (25), and an optical component (15). The illumination device (10) includes the optical component (15) having an average reflectance in the wavelength range 400 nm to 500 nm lower than an average reflectance in the wavelength 500 nm to 800 nm, a fluorescence generator (18), a wavelength selector (16) having a first area (163) and a second area (161, 162, 164), a polarization converter (14) and an optical-path switcher (13). The wavelength selector (16) alternately sets the first area (163) and the second area (161, 162, 164) in an optical path of a first light in a temporal manner. The illumination device (10) switches a first optical path and a second optical path based on a setting of the wavelength selector (16).

    摘要： An image projection apparatus (1) includes a light source (3), a color wheel (4), a controller (103). The controller (103) controls, in a first mode, electric power supplied to the light source (3) at a timing of a first color filter being irradiated with light from the light source (3) to be a value higher than electric power supplied to the light source at a timing of a second color filter corresponding to a color having lower visibility than a color of the first color filter being irradiated with the light from the light source (3). Furthermore, the controller (103) controls, in a second mode, the electric power supplied to the light source (3) at the timing of the first color filter being irradiated with the light from the light source (3) to be a value lower than the electric power supplied to the light source at the timing of the second color filter being irradiated with the light.
