Abstract:
A vehicle lamp includes a light source configured to emit light, a liquid crystal element configured to variably modulate a polarization state of the light emitted from the light source, a condensing optical system configured to condense the light emitted from the light source toward the liquid crystal element, a polarization beam splitter configured to transmit light containing one of polarized components of the light condensed by the condensing optical system toward the liquid crystal element and configured to reflect light containing the other polarized component of the light condensed by the condensing optical system toward the light source, and a scattering and reflecting member disposed at a surrounding of the light source and configured to scatter and reflect the light reflected by the polarization beam splitter toward the condensing optical system.
