Projection image apparatus

A projection image apparatus comprising:

• a light source that emits laser light of a first color that is blue and laser light of a second color different from blue;
• an illumination optical system that generates illumination light by combining the laser light of the first color and the laser light of the second color from the light source;
• a light modulator that generates image light by modulating the illumination light from the illumination optical system in response to an image signal input from an outside;
• and
• a projection optical system that enlarges the image light emitted from the light modulator and projects the image light onto a projection target,
• wherein
• the light source includes:
• a first light source component including a plurality of first laser light emitters arranged in an array, and each configured to emit the laser light of the first color, and
• a second light source component including a plurality of second laser light emitters arranged in an array, and each configured to emit the laser light of the second color,
• an area of a light emitting surface of the first light source component is different from an area of a light emitting surface of the second light source component,
• the illumination optical system includes a relay optical system that guides the illumination light to the light modulator,
• the light source further includes an optical system that changes at least one of a height of a light source image of the laser light of the first color or a height of a light source image of the laser light of the second color,
• the optical system of the light source is configured to have a small difference between the height of the light source image of the laser light of the first color and the height of the light source image of the laser light of the second color,
• the relay optical system includes a first diaphragm of reflection type having a variable opening diameter, the first diaphragm disposed at a first pupil position where the illumination light is condensed, and
• the projection optical system includes a second diaphragm of absorption type having a variable opening diameter, the second diaphragm disposed at a second pupil position conjugate with the first pupil position.
