Application of Holography: 3D Hologram Projector

Abstract

An electrical tool used to project images is called a projector. They may be able to educate more effectively and make better use of class time as a result. This research focuses on building a DIY small projector. Despite being quite expensive, the projector is very useful for teachers. Instead of tossing away items which deem to be of no value at all, we thought about creating a projector inexpensively. On the basis of the various experiments we've conducted, we're attempting to recycle those materials to create a small projector. We constructed the projector out of cardboard, and to check the clarity of the image, we used a magnifying lens and several forms of lighting. and to be aware of the outcomes of our experiments. We used the projector to give small children a little narrative and it was tested during that time. As a consequence, we saw that the kids pay close attention and seem to like the narrative. We demonstrated that teachers may utilise a DIY tiny projector effectively and affordably, especially when instructing young students.
