Equipments
Opaque projector
Is a device which displays opaque materials by shining a bright lamp onto the object from above.
Video Projector
- Is an image projector that receives a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and
most modern ones can correct any curves, blurriness, and other
inconsistencies through manual settings.
Overhead Projector
-Is a variant of slide projector that is used to display images to an audience. An overhead projector typically consists of a large box containing a
very bright lamp and a fan to cool it. On top of the box is a large fresnel lens that collimates
the light. Above the box, typically on a long arm, is a mirror and lens
that focuses and redirects the light forward instead of up.
Slide Projector
-is an opto-mechanical device to view photographic slides.
Slide projectors were common in the 1950s to the 1970s as a form of
entertainment; family members and friends would gather to view slide shows. In-home photographic slides and slide projectors have largely been replaced by low cost paper prints, digital cameras, DVD media, video display monitors, and video projectors
