pst-diffrac­tion – Print diffrac­tion pat­terns from var­i­ous aper­tures

The pack­age en­ables the user to draw the diffrac­tion pat­terns for dif­fer­ent ge­o­met­ric forms of aper­tures for monochro­matic light. The aper­ture stops can have rect­an­gu­lar, cir­cu­lar or tri­an­gu­lar open­ings. The view of the diffrac­tion may be pla­nar, or three-di­men­sional.
Op­tions avail­able are the di­men­sions of the aper­ture un­der con­sid­er­a­tion and of the par­tic­u­lar op­ti­cal set­ting, e.g. the ra­dius in case of an cir­cu­lar open­ing. More­over one can choose the wave­length of the light (the as­so­ci­ated color will be cal­cu­lated by the pack­age).
