- International Year of Light, 2015
The International Year of Light and Light-Based Technologies (IYL 2015) is a global initiative adopted by the United Nations to raise awareness of how optical technologies promote sustainable development and provide solutions to worldwide challenges in energy, education, agriculture, communications and health. The goal of IYL 2015 is to highlight to the citizens of the world the importance of light and optical technologies in their lives, for their futures and for the development of society.
2015 is also the anniversary of some important milestones in the history of science. It includes the publication of Ibn Al-Haytham's "Book of Optics" in 1015, the notion of light as a wave proposed by Augustin-Jean Fresnel in 1815, the electromagnetic theory of light propagation proposed by James Clerk Maxwell in 1865, Einstein's theory of the photoelectric effect in 1905 and of the embedding of light in cosmology through general relativity in 1915, the discovery of cosmic microwave background by Arno Penzias and Robert Wilson, and Charles Kao's achievements concerning the transmission of light in fibers for optical communication in 1965. The IYL 2015 is not only a tribute to the science pioneers, but also highlights the contribution of the development of optics and optoelectronic technology to the sustainable development of human in future. It also encourages and inspires more young people to join the field of optical science and technology.

Public Activities
Interactive Exhibit: Optical Phone
The concept of "Optical Phone" originates from the photophone proposed by Alexander Bell. After his invention of telephone in 1876, Alexander Bell continued and soon successfully experimented on the photophone, which he regarded it as his greatest inventions. When the visitor takes up the torch of the exhibit, points the light beam at the receiver on the opposite side and talks to the phone, the light beam will change according to the voice. Light signal will be transformed into electric signal through the receiver so that the recipient can hear the voice of the sender on the phone. Therefore, visitors can operate the "Optical Phone" as a "wireless phone", and share the excitement of photophone invention by Alexander Bell more that a hundred years ago.
Workshops of LED's Changing Looks
A. LED Festival
Light-Emitting Diode (LED) is a two-lead semi-conductor light source. Nowadays it is widely used in monitors, lighting, etc. The research on LED started in 1907 when the British scientist, Henry Joseph Round, discovered that silicone carbide will illuminate with a current flow of electricity. However, only until 1962 did LED start to be commercialized when infrared LED was developed. The 2014 Nobel Prize in Physics was awarded to two Japanese scientists and one American scientist for their inventions of high-brightness blue LED which has brought a bright and energy-saving white light source to the world. Participants will learn the basic theories of LED and make a festive lamp stand in the workshop.

SciTech Talk - Optogenetics
Optogenetics is a combination of techniques from optics and genetics to precisely control the activities of individual cells in time and space. Time can be precisely measured in millisecond and space can be measured by the size of individual cells. In 2005, when the scientists first applied channelrhodopsin to neurons, they discovered that blue light can accurately control the activation of neurons. Since then the term Optogenetics arises.
The seminar is jointly organized with the Macau Society of Biomedical Engineering to introduce the development and application of cutting-edge echnology to secondary students and teachers. It is hoped to encourage more young people to be more aware of and join the study and research of biomedical engineering.

Item: S3-E02 "Application of Photodiode - Photosensitive Mechanical Beetle"
Audience: Form 3 or above, completion of S3-E01 is recommended
Duration: 4 weeks, 10 hours
Content:
Students will be introduced about LEDs, photodiodes, NPN type transistors, DC motor and their application as a whole. They will use the above-mentioned components to build a photosensitive mechanical beetle, which follows light to guide its way.
LED is a semiconductor component widespread and popular due to its long service life, versatile color changing ability and low power consumption. Applications of LEDs are so diversified in fabrication of indicator light, display boards and lighting that they show many advantages over traditional light sources, such as lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching.
A photodiode is a typical photo detector which is capable of converting light into either current or voltage, depending upon the mode of operation. It is usually found in automatic control system.
Transistor is a semiconductor device commonly used to amplify or switch electronic signals. The NPN transistor used in this course is like a switch where the input voltage is applied to change the output current. Unlike other mechanical switches, transistor can use electrical signals to control the switch "on" and "off" with high speed.

Item: S3-E05 "Application of Infrared Communication Technology"
Audience: Form 4 or above
Duration: 4 weeks, 10 hours
Content:
Infrared (IR) is an electromagnetic wave whose wavelength is longer than visible light but shorter than microwave. Since no physical connection and no complicated components are needed for IR communications, the cost of transmission is lower. This explains why it has become a common technology applied in portable computer, mobile phones and other transmission equipment for data transfer. It is also used in the remote control of TV, air-conditioner and other household appliances.
This course allows students to experience the applications of infrared in our daily life by making gadgets by themselves. Participants will produce an infrared receiver that connects to the computer and use an ordinary household remote control to substitute the operation of the mouse or keyboard of the computer.
Charge:
Held in the museum - MOP50.00 per student. This course cannot be done at schools because oscilloscopes are needed.
Outline:
Lesson 1 - Introduction to 555 monostable oscillating circuit.
Lesson 2 - Introduction to infrared communication technology and making the receiver.

Content:
The infrared rays from an Infrared LED can pass through human skin. When the heart beats, blood flows through the blood vessels inside our fingers. At the same time, the infrared rays received by the photodiode also changes, which results in a weak electric signal. When this electric signal is magnified by an operational amplifier, which in turn lights up an LED, we can observe the heart rate. In this course, participants will learn how to make a simple Heart Rate Monitor and learn about the application of operational amplifier in our daily life.
