An article of manufacture including a computer readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
- recording a first hologram containing primarily content of a first primary color of an intended composite hologram;
- recording a second hologram containing primarily content of a second primary color of the intended composite hologram;
- recording a third hologram containing primarily content of a third primary color of the intended composite hologram;
- transmitting, using a first filter, at least a portion of wavelengths close to the first primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- blocking, using the first filter, at least a portion of wavelengths close to the second primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- blocking, using the first filter, at least a portion of wavelengths close to the third primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- blocking, using the first filter, at least a portion of wavelengths close to the first primary color at angles close to a replay reference angle of the second hologram for the first primary color;
- blocking, using the first filter, at least a portion of wavelengths close to the first primary color at angles close to a replay reference angle of the third hologram for the first primary color;
- transmitting, using the first filter, at least a portion of wavelengths close to the second primary color at angles close to a replay reference angle of the second hologram for the second primary color;
- transmitting, using the first filter, at least a portion of wavelengths close to the third primary color at angles close to a replay reference angle of the third hologram for the third primary color;
- transmitting, using a second filter, at least a portion of wavelengths close to the first primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- transmitting, using the second filter, at least a portion of wavelengths close to the second primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- blocking, using the second filter, at least a portion of wavelengths close to the third primary color at a broad range of angles about an intended viewing angle of the intended composite hologram;
- transmitting, using the second filter, at least a portion of wavelengths close to the third primary color at angles close to the replay reference angle of the third hologram for the third primary color;
- blocking, using the second filter, at least a portion of wavelengths close to the second primary color at angles close to a replay reference angle of the third hologram for the second primary color;
- assembling the holograms and filters as the intended composite hologram in the order first hologram, first filter, second hologram, second filter, third hologram;
- and
- replaying the composite hologram using a light source of the first primary color incident upon the assembly only at angles close to a replay reference angle of the first hologram for the first primary color,
- a light source of the second primary color incident upon the assembly only at angles close to the replay reference angle of the second hologram for the second primary color, and a light source of the third primary color incident upon the assembly only at angles close to the replay reference angle of the third hologram for the third primary color.
