摘要： An illumination unit of the present disclosure includes an excitation light source, a phosphor section, an excitation-light intensity distribution generation section, and an illumination optical system. The excitation light source emits excitation light. The phosphor section includes a fluorescent light-emission surface that performs fluorescent light emission in response to receiving of the excitation light. The excitation-light intensity distribution generation section is provided between the excitation light source and the phosphor section, and varies an intensity distribution of the excitation light to bring the intensity distribution of the excitation light closer to a desired excitation-light intensity distribution on the fluorescent light-emission surface. The illumination optical system generates, on the basis of light derived from the fluorescent light emission from the phosphor section, illumination light with which an image display device is to be irradiated.

摘要： A light source unit according to an embodiment of the disclosure includes a substrate configured to be rotatable, a phosphor layer disposed at a center of the substrate, a light source that irradiates the phosphor layer with exciting light, and a support section that supports a portion, of the substrate, except for the center of the substrate. This makes it difficult for heat generated in the phosphor layer to travel to a motor through the substrate.

摘要： A phase modulation data generating unit according to the present disclosure includes: a first calculating section; and a storage section. The first calculating section calculates basic phase modulation pattern data on the basis of a partial illumination image pattern that makes it possible to generate an intended illumination image pattern having a desired luminance distribution. The basic phase modulation pattern data makes it possible for a light phase modulation device to reconstruct the partial illumination image pattern. The storage section stores the basic phase modulation pattern data calculated by the first calculating section.

摘要： A first projection display apparatus includes a color separator (41A) that has first and second incident surfaces (S1a and S1b), and allows light in first to third wavelength bands to pass therethrough or reflects the light in the first to third wavelength bands; first to third reflective light modulators (15); a first polarization splitter (12G); a second polarization splitter (12RB); and a projection optical system (19). Light in at least one of the first to third wavelength bands enters the first incident surface of the color separator as first polarized light, and light in the other wavelength bands enters the second incident surface of the color separator as second polarized light orthogonal to the first polarized light.
