Segmented spiral phase plate
Summary edit
| Description |
English: A spiral phase plate composed of multiple segments. It demonstrates that the design of actual phase plates suffers from limited manufacturing capabilities and the smooth helical profile is hard to achieve. Čeština: Spirální fázová destička složená z mnoha segmentů. Ukazuje, že design skutečných destiček je volen s ohledem na omezené výrobní schopnosti a že dosáhnout hladkého šroubovicového povrchu je náročné. |
