Title: System and method for portable multi-band black body simulator

Abstract

The present disclosure relates to an apparatus for simulating a black body spectrum. The apparatus makes use of a broadband light source and a light guide configured to receive light generated by the light source and to generate first and second optical signals. A first signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the first optical signal. A second signal processing subsystem may be used to enable adjustment of both a signal spectrum and an intensity of the second optical signal. A beam cube may be used to combine the first and second optical signals to produce a final light output signal having a desired signal spectrum and a desired intensity.
