1. A non-invasive method applied to a life object, comprising:

  • irradiating the life object with a first electromagnetic wave having a prescribed wavelength, the prescribed wavelength being included in a range from 1.028 μ

    m to 2.50 μ

    m;

    setting a position of a detected area related to a depth below a surface of the life object; and

    detecting a signal relating to a second electromagnetic wave, the second electromagnetic wave having a wavelength same as the prescribed wavelength, the second electromagnetic wave being obtained from the detected area, and at least a part of the second electromagnetic wave being condensed out of the life object; and

    detecting neural activity in the life object based on the detected signal, the neural activity relating to a nerve impulse of neuron.
