In the fifth century B.C., the Chinese philosopher Mo Ti noted that a pinhole can form an inverted and focused image, when light passes through the hole and into a dark area. Mo Ti is the first recorded person to have exploited this phenomenon to trace the inverted image to create a picture. Writing in the fourth century B.C., Aristotle also mentioned this principle. He described observing a partial solar eclipse in 330 B.C. by seeing the image of the Sun projected through the small spaces between the leaves of a tree.[/vc_column_text][/vc_column][vc_column width=”1/6″ tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column][/vc_row][vc_row section=”yes” full_width=”full” tooltip_color=”color1″ tooltip_text_color=”color3″ color=”color6″][vc_column width=”1/1″][ish_slidable animation=”fade” nav_align=”center” nav_position=”inside” nav_color=”color4″ prevnext_color=”color4″ interval=”5″ tooltip_color=”color1″ tooltip_text_color=”color3″ max_height=”600″][ish_slide title=”Slide Title”][vc_row_inner][vc_column_inner width=”1/1″][ish_image image=”2010″ size=”full” stretch_image=”yes” tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column_inner][/vc_row_inner][/ish_slide][ish_slide title=”Slide Title”][vc_row_inner][vc_column_inner width=”1/1″][ish_image image=”2010″ size=”full” stretch_image=”yes” tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column_inner][/vc_row_inner][/ish_slide][ish_slide title=”Slide Title”][vc_row_inner][vc_column_inner width=”1/1″][ish_image image=”2010″ size=”full” stretch_image=”yes” tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column_inner][/vc_row_inner][/ish_slide][/ish_slidable][/vc_column][/vc_row][vc_row section=”yes” color=”color1″ text_color=”color6″ tooltip_color=”color1″ tooltip_text_color=”color3″][vc_column width=”1/6″ align=”center” tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column][vc_column width=”2/3″ align=”center” tooltip_color=”color1″ tooltip_text_color=”color3″][ish_icon icon=”ish-icon-hearing-impaired” type=”simple” align=”center” color=”color7″ size=”60″ tooltip_color=”color1″ tooltip_text_color=”color3″ text_color=”color7″][ish_headline tag_size=”h2″ icon_align=”left” tag=”h” tooltip_color=”color1″ tooltip_text_color=”color3″]Reference[/ish_headline][ish_separator color=”color7″ type=”thin” align=”center” width_percent=”10″ tooltip_color=”color1″ tooltip_text_color=”color3″][vc_column_text tooltip_color=”color1″ tooltip_text_color=”color3″]In the tenth century, the Arabic scholar Ibn al-Haytham (Alhazen) also wrote about observing a solar eclipse through a pinhole, and he described how a sharper image could be produced by making the opening of the pinhole smaller. English philosopher Roger Bacon wrote about these optical principles in his 1267 treatise Perspectiva. By the fifteenth century, artists and scientists were using this phenomenon to make observations.[/vc_column_text][ish_separator color=”color7″ type=”thin” align=”center” width_percent=”10″ tooltip_color=”color1″ tooltip_text_color=”color3″][vc_column_text tooltip_color=”color1″ tooltip_text_color=”color3″]Originally, an observer had to enter an actual room, in which a pinhole was made on one wall. On the opposite wall, the observer would view the inverted image of the outside. The name camera obscura, Latin for “dark room”, derives from this early implementation of the optical phenomenon. The term was first coined by mathematician and astronomer Johannes Kepler in his Ad Vitellionem paralipomena of 1604.[/vc_column_text][/vc_column][vc_column width=”1/6″ tooltip_color=”color1″ tooltip_text_color=”color3″][/vc_column][/vc_row]
