Method and notch reflector projection system

A system comprising:

• a visor arranged across the aperture and comprising a transparent material;
• a projection system configured to project visible light within a first output channel and within a second output channel, in the form of a composite color image, onto the visor, the first output channel spanning a first band of wavelengths of visible light and the second output channel spanning a second band of wavelengths of visible light distinct and offset from the first band of wavelengths of visible light;
• a reflective coating:
• applied across the visor;
• configured to selectively reflect wavelengths of incident visible light, incident within a first reflection channel overlapping the first output channel;
• configured to selectively reflect wavelengths of incident visible light within a second reflection channel overlapping the second output channel, the second reflection channel distinct and offset from the first reflection channel;
• and
• configured to transmit wavelengths of visible light outside of the first reflection channel and the second reflection channel.

A method comprising:

• at a projection system:
• projecting visible light within a first band of output wavelengths onto a visor, the first band of output wavelengths corresponding to a first color component;
• and
• projecting visible light within a second band of output wavelengths onto the visor, the second band of output wavelengths corresponding to a second color component and distinct and offset from the first band of output wavelengths;
• at a visor:
• reflecting incident visible light within a first band of reflection wavelengths, the first band of reflection wavelengths overlapping the first band of output wavelengths;
• reflecting incident visible light within a second band of reflection wavelengths, the second band of reflection wavelengths overlapping the second band of output wavelengths and distinct and offset from the first band of reflection wavelengths;
• transmitting visible light outside of the first band of reflection wavelengths and outside of the second band of reflection wavelengths.
