I read the tutorial on http://www.3dimagery.com/ on how to create a white light reflecting hologram but the He-Ne laser is too expensive for me . So I want to ask that can I use inexpensive laser diodes in the place of He-Ne gas lasers .
Besides that I see the websites say that the transmisson hologram can produce a virtual and real image but I don't it doesn't say white light reflecting can also produce a real image ( the image in front of the hologram plate ) . So , I want to ask that can a white light reflecting hologram produce a real image ?
