摘要： A microlens array includes N lenses ranging from a 1st lens to an Nth lens and a lens arrangement area. N is a positive integer. The lens arrangement area has the N lenses arranged in array. The lens arrangement area receives light emitted from a light source. An ith (i being 1st to Nth) lens satisfies a conditional expression below: −20°≤θ≤20° where θ denotes an angle formed by a main-axis orientation of double refraction and a reference orientation.

摘要： An image display device includes a display unit configured to display a display image and to use a color information target value as a color information value of a display color, the display color being a color of the displayed image; and a first image correction unit configured, in a case where the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit is different from the color information target value, to correct the color information value of the display color of the displayed image displayed by the display unit, so that the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit becomes the color information target value.

摘要： An image display apparatus includes a light source emitting light; an optical scanner scanning a predetermined scanning zone with light from the light source to render a display image; a light intensity detector detecting a light intensity of light from the light source; a memory storing relationships between control currents provided to the light source and light intensities; and one or more processors controlling, on the basis of the control current and light intensity relationships stored in the memory, a control current to display the display image with light from the light source. When the optical scanner scans an area outside the display image, the one or more processors detect by the light intensity detector a light intensity of light for the scanning, and update on the basis of the light intensity the relationships stored in the memory.

摘要： A semiconductor laser is for generating colored light. The semiconductor laser oscillates in a longitudinal multimode. A width of a wavelength band with an intensity equal to or more than −20 dB relative to a peak intensity in a spectrum distribution of output light is equal to or less than 15 nm. A light source device may include The semiconductor laser; a wavelength estimating device configured to estimate a wavelength λ of light from the semiconductor laser; and an emission-light intensity setting unit configured to set an emission light intensity of the semiconductor laser in accordance with an estimation result by the wavelength estimating device.
