Abstract: A color synthesizing apparatus includes a white light source configured to output a collimated beam, a line beam generator configured to receive the collimated beam and generate a line beam spatially separated depending on a wavelength, a first parabolic mirror configured to receive the line beam provided by the line beam generator and provide a parallel light, a second parabolic mirror configured to receive the parallel light of the first parabolic mirror and focus the received parallel light on a focal point, a spatial variable spectral filter disposed between the first parabolic mirror and the second parabolic mirror and configured to transmit different wavelengths depending on positions, and a spatial light modulator disposed between the spatial variable spectral filter and the second parabolic mirror and configured to provide different transmittances depending on the positions.
