    摘要： Provided are a speckle removing light source capable of removing speckle by using laser light whose wavelength is temporally changed and a lighting apparatus for producing an image from which the speckle is removed. Provided is a speckle removing light source, including: a light source for outputting laser light; and a light frequency modulator for changing a wavelength of the laser light, in which: the wavelength of the laser light outputted from the light source is temporally changed by the light frequency modulator; and the light frequency modulator has a predetermined period set for changing the wavelength of the laser light. Also, provided is a lighting apparatus, including: a spatial light modulator illuminated with the laser light outputted from the speckle removing light source to produce an image, in which the spatial light modulator has a period set for producing the image, and the period is longer than the period for changing the wavelength of the laser light by the light frequency modulator.
