Colors2014 Winner   
By Gustavo Almeida, Adriano Otuka, Emerson Barbano, Renato Juliano Martins, Nathalia Tomazio, and Franciele Renata Henrique, Universidade de Sao Paulo, Sao Paulo, Brazil

Our video explains how screen devices produce the colors we see. We introduce a few information of the transition from black and white TVs to colors ones and ask the audience how many colors screen devices are able to reproduce. With three LEDs we demonstrate the RGB additive method and recording cell phones screens under a microscope we show real devices working. Then, we say that a pixel is able to produce around 17 million colors.

How a DVD Drive Works!2014 Entry   
By Kamran Qaderi, Brigham Young University, Utah, USA

I have explained the basic idea to how a DVD drive works, and I have sketched the design for a DVD drive and explained the details for each piece of it. What I have prepared in the video is a basic idea how a DVD drive works, I could not cover all detailed parts because of timing.

How has Optics Enabled a Wireless Optical Mouse?2013 Entry   
By Mikhail Shalaginov, Purdue University, USA

In this video we take apart a wireless optical mouse and demonstrate four important optical components which enable its functionality.

Laser Barcode Scanner2013 Entry   
By Pavel Voroshilov, Saint Petersburg National Research University of Information Technologies, Mechanics and Optics, Russian Federation

Optical components are widely used in modern information processing and transmission systems. One of such devices is a laser bar scanner. We decided to find out what kind of optical components are used in a scanner.

Liquid Crystal Displays2014 Entry   
By Jack Devine, University of Otago, Otago, New Zealand 

In this video I briefly discuss the exciting technology behind Liquid Crystal Displays. I begin by talking about their consumer applications. Then, I discuss the polarization of light with a simple demonstration. Finally, I discuss how the twisted nematic effect is used in display technologies to create an array of pixels at varying degrees of illumination.

LCD monitors bring us to an exciting world with a magic vision...Can we image a life without LCD monitors? This video will bring you to the spirit of Optics!

Optics, the Heart of High Speed Worldwide Communications2013 Entry   
By Clément Javerzac-Galy, Ecole Polytechnique Fédérale de Lausanne and Institut d'Optique Graduate School, France

All kinds of optics are hidden behind your laptops and phones. Everytime you exchange information, it is processed by optical technologies. This is what we try to show in this video; the contrast between the simplicity of sharing data with a phone and the beauty of the optics that actually enables it. We used all our passion for optics in this video trying to emphasize how optics interconnects the world. We finally try to give glimpses on the future of (green/all optical) communications.

Second-Harmonic Generation Phenomena in "Green" Laser Pointer2014 Entry   
By Rostyslav Danylo, Olena Polianska, and Yevheniia Chernukha, Taras Shevchenko National University of Kyiv, Kyiv, Ukraine

We present on the video a laser pointer. It’s a modern product permitting to indicate faraway objects. The idea of the video is to show the interior construction of the pointer to the audience. We want to describe the elements the pointer consists of and demonstrate product’s optical scheme. We saw up the frame of the pointer. We separate gradually different optical elements and describe their importance. In fact we see the edge of the gain media and the mirror deposed on it.

Security Holograms! 2014 Entry   
By Laura Mari Pulido Mancera, Sylvia Patricia Ceballos, Ivan Pulido, and Andrea Pacheco, Universidad Nacional de Colombia, Bogota, Colombia

This video shows the basics and importance of security holograms for advertising and anti-counterfeit in several products like pharmaceutical drugs, innovative arts and advertising tickets. We include some videos about the research and manufacture of holograms in Colombia. We explain that holograms by themselves are First level security. This means that only the observation of the hologram give us information about the reliability of any product. We participate as the OSA-Student Chapter UNBOS.
