pseudoscope การใช้

• In 1853 the American scientist John Leonard Riddell ( 1807-1865 ) devised his binocular microscope, which contained the essentials of Wheatstone's pseudoscope.
• The'pseudoscope'( Wheatstone coined the term from the Greek ?????? ??????? ) was introduced in 1852, and is in some sort the reverse of the stereoscope, since it causes a solid object to seem hollow, and a nearer one to be farther off; thus, a bust appears to be a mask, and a tree growing outside of a window looks as if it were growing inside the room.
