“…Some students work on interferometric holography 17,18 using reflection or transmission configurations. Several students work on pseudo colour holograms [19][20][21] and one student had work on a computer program to produce computer generated holograms 22,23 . Some secondary students and several younger students are working on scratch holograms [24][25][26] .…”

“…The activities for schools have the name holography@school and the activities for holography outreach have the name holography4all. Holography@school, based on teacher training and experimental workshops for students, includes the following topics: setting up an experimental configuration, beam alignment, spatial filter manipulation, reflection holograms 2 , transmission holograms 10 , pseudo colour holograms (multi colour) 19 , emulsion preparation, holographic interferograms 17 , computer generated holograms 23 and scratch holograms [24][25][26] . The holography@school sessions happen at the Holography Club of the school, during the scholar year and it involves students and a supervisor teacher.…”

Holography is an optics technique based on wave physics and lasers with several applications at our day life. The production of holograms involves experimental work based on hands-on activities and creativity. All these elements can contribute to the promotion of experimental teaching of optics and training on holography. The hologram itself acting as a final result from a long process of research and study can enable the engagement of high school students on physics and promote the stimulus on optics learning. Taking these assumptions into account a network of schools working on holography was built involving thirty schools from all country. Holography systems were developed and several handson activities were constructed. During last sixteen years students are working on laser optics and holography producing different kinds of holograms. This study presents all holography labs implemented at schools and it will analyzed the holography systems and materials developed for students. Training strategy will be discussed and holograms obtained by students will be presented. Results obtained show us that holography can be implemented as a strategy for promoting the learning of optics and it is a particular way to involve students on experimental work and lab research. Results obtained during this study will be presented in detail and analyzed with focus on students performance. Educational results, teachers training, prizes and other positive outcomes will be discussed and compared.

“…Digital holography is the digital recording and numerical reconstruction of holographic data. Digital holography also includes optical construction and digital reconstruction [1] of data as well as digital construction and optical reconstruction [2] of data. In this paper, both the construction and reconstruction of hologram are done in digital domain with the aid of mathematical models.…”
