Black absorbs light, and white reflects light. That's why you're advised to wear white on warm sunny days. And that also happens to be the basic mechanism of the barcode scanner!
This video aims to describe by using some LEDs how function a play of light used to decorate some Christmas trees.
Ever wondered what your cell phone camera looks like from the inside? Ever wonder how it works? In this video, we explore the optical technology behind the camera capture devices in cell phones and digital cameras. We have a brief overview about CMOS sensors and CCD arrays, and how the photoelectric effect makes digital picture-taking possible.
Minidisc players use a diode laser to write/read the disc. Mine's broken, but I thought it might be fun to sample the sounds it can make to make a song about how it functions
In this video, we show you how we disarm a CD-DVD reader at our physics lab and we explain its functionality, both their recorded and reproduction of the disc. Made by Cristhian Garcia Toledo, Richard Vilca Sagastegui and Gaston Lozano Calderon, UNFV
IIn the video is shown great importance of opitcal system in our daily life and how this system works. This video was made in Peru, where a group of students chose DVD due to major value interactive and playing with different types of people of different ages.
It is about the headlights and flashlights and their optical components
In this video we take apart a wireless optical mouse and demonstrate four important optical components which enable its functionality.
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.
Operating principle of sound transmission by optical fiber.
We all use optical mouse in our daily life but only a few know about how it works, even without any wires (wireless mouse). So we would like to describe that along with the history of mouse invention.
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!
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.
This video shows how optics as a technology play a vital role in a day-to-day use of a remote control, making it a useable product for the consumer. Meanwhile, a brief overview of the electronic components and how they work simultaneously with the optical part is given.
The microwave generator produces a fog curtain that reflect the image.
This video tells about how to avoid road accident in T-junction road using a Trixi mirror.
