Methods and systems of determining quantum efficiency of a camera

A color calibration system comprising:

• at least one broad spectrum light emitting diode configured to transmit light;
• a camera, the camera comprising at least one sensor for detection of colors from the light;
• and
• means for limiting wavelengths of light received by the at least one sensor,
• wherein the light is used to calibrate the at least one sensor.

A method of performing color calibration comprising:

• transmitting light from at least one broad spectrum light emitting diode;
• scattering light with at least one light diffuser plate;
• filtering light with at least one interference filter;
• detecting light at a camera sensor;
• mapping an intensity value for each pixel of the camera sensor;
• and
• creating at least one quantum efficiency curve for each of red, green, and blue channels.

A colorimetric calibration system comprising:

• a chromatic projector contained in a housing, the chromatic projector comprising:
• a light source, the light source connected to a power source;
• a light diffuser plate;
• and
• an array comprising a plurality of narrow-band interference filters,
• wherein light is configured to travel from the light source, through the light diffuser plate, and through the plurality of narrow-band interference filters.

A chromatic projector comprising:

• a housing:
• a power source disposed within the housing;
• an array of narrow-band interference filters disposed within the housing, each narrow-band interference filter of the array being separated from other narrow-band interference filters of the array by at least one separator wall to prevent crosstalk;
• at least one light source disposed within the housing and coupled to the power source;
• and
• at least one light diffuser plate disposed within the housing between the array and the at least one light source, wherein the at least one light source is configured to emit light through the array via the at least one light diffuser plate.
