Method of assessing the effectiveness of a laser eye protection device

摘要

A method of assessing the effectiveness of a laser eye protection (LEP) device having an interference filter surface (IFS) includes (A) specifying optical densities at a number of points on the IFS for a user specified range of incident angles of a given wavelength of laser light at each of the number of points; (B) entering the specified optical densities into a computer; (C) entering properties of the IFS into the computer; (D) entering properties of an eye into the computer; (E) entering properties of the given wavelength of laser radiation into the computer; (F) defining a grid for the IFS and assigning values of optical densities to points on the IFS grid using the optical densities from step (A) and interpolation; (G) assigning different colors to different optical densities, respectively; (H) generating and displaying a three-dimensional image of the eye and IFS using a graphical user interface (GUI); (I) using the GUI, selecting an incident angle orientation for the given wavelength of laser light and coloring the IFS as a function of optical density on the IFS; (J) using the GUI, selecting an eye orientation and projecting a pupil surface onto the IFS at a point of interest along the incident angle selected in step (I); and (K) determining an average optical density for that portion of the IFS intersected by the projected pupil surface of step (J) and coloring the portion in accordance with the determined average optical density.
