System and method for portable multi-band black body simulator

A multi-band black body simulating apparatus, the apparatus comprising:

• a broadband light source;
• a light guide configured to receive light generated by the light source and generating first and second optical signals;
• a first signal processing subsystem for enabling adjustment of both a signal spectrum and an intensity of the first optical signal, the first signal processing subsystem including:
• a first bandpass filter;
• and
• a first adjustable optical attenuator;
• a second signal processing subsystem for enabling adjustment of both a signal spectrum and an intensity of the second light optical signal, the second signal processing subsystem including:
• a second bandpass filter;
• and
• a second adjustable optical attenuator;
• a beam cube configured to combine the first and second optical signals received from the first and second signal processing subsystems to produce a final light output signal.

A method for simulating a black body, the method comprising:

• using a broadband light source to generate broadband light;
• using a light guide to receive the broadband light and to generate first and second optical signals;
• using a first signal processing subsystem to receive the first optical signal and to enable user adjustment of both a signal spectrum and an intensity of the first optical signal;
• using a second signal processing subsystem to receive the second optical signal and to enable adjustment of both a signal spectrum and an intensity of the second light optical signal;
• and
• using a beam cube configured to combine the first and second optical signals to produce a final light output signal having a desired signal spectrum and a desired intensity.
