Hasan ibn al-Haitsam (Ibn Al-Haytham) or better known as Alhazen is a Muslim scholar who is skilled in science, falak, mathematics, geometry, medicine, and philosophy. He has also done research on light, and has provided much inspiration to Western science experts, such as Roger Bacon, and Kepler in creating microscopes and telescopes. He was born in 965 A.D. in Bashrah, Iraq.
In general, Alhazen is also the first person to learn how to work the eye to see. In the 10th century he made his own first camera. The camera that was first created was the camera obscura or better known as a pinhole camera. This item shows how light can be used to project an image on a flat surface. When making this first camera, Alhazen performs a series of experiments on optics. In his various experiments, Ibn Al-Haitham used the term "Al-Bayt al-Muthlim " which translates as dark space.

He made a very thorough experiment on the trajectory of light through several mediums and found a light refruse theory. He is also the first to experiment on spreading light against multicolored colours. Ibn Haitham also explained about the variety of light that arose at sunset, including theories of appearance of Shadows, eclipses, and rainbows. The Iraqi scientist was noted as the first person to describe the senses of human vision in detail. No exception, about the process human beings can see.
One of his most phenomenal books is Al-Manadhir which is widely translated into Latin in his time to help the development of human civilization. But unfortunately, the original book of Al-Manadhir is currently unknown to his existence.
