Abstract
Described examples include an optical device, having a light source with a light source output and a light integrator having a light integrator input and a light integrator output, the light integrator input optically coupled to the light source output, and the light integrator configured to provide divergent light at the light integrator output responsive to the light at the light source output. The optical device also has projection optics with an optics input and an optics output, the projection optics configured to project output light at the optics output responsive to modulated light at the optics input, in which a focal point of the optics input matches a divergence of the modulated light and a spatial light modulator optically coupled between the light integrator output and the optics input, the spatial light modulator configured to provide the modulated light responsive to the divergent light.
