ABSTRACT:
A method for generating holographic optical elements such as power spectrum filters is carried out using a printer and a computer. A signal function is input into the computer and traced by the printer to produce a power spectrum envelope of the signal function. The power spectrum is then filled in with a grating pattern whose line spacing is determined by the desired diffraction of coherent radiation beams used to interrogate the optical element.
