1. A patterned substrate spectrometer, comprising:

  • a test substrate;

    a spatial pattern of chemically active substances for binding chemical or biological samples distributed across the test substrate according to a mathematical function;

    a diffractive element;

    a detector array;

    a radiation source that emits radiation onto the spatial pattern;

    one or more optical components that guide radiation radiated by the spatial pattern from the test substrate through the diffractive element and onto the detector array; and

    a processor that receives an optical intensity from the detector array and calculates a mean spectrum of the spatial pattern from the optical intensity and the mathematical function.
