Abstract
An optical module includes: a diffraction grating configured to rotate and focus a beam, which is incident thereon from an incident path, onto a Fourier plane, a digital micromirror array (DMD) configured to assign a frequency for each wavelength of the focused beam received at the Fourier plane, and perform a Fourier transform for each frequency, and a first optical fiber configured to receive a beam that is reflected back from the DMD back and the diffraction grating, and along the incident path.
