PE-1000 CCD Camera & Night Vision
The principle of creating an image through projection on a surface is known since ancient times. Aristotle observed images of the sun through holes generated by the leaves of a tree, while Arab scientists used this principle in astronomy to observe the solar eclipses. The most clear and detailed description is made by Leonardo da Vinci in his work “Codice Atlantico” where for the first time, the structure of the human eye is commented as a “camera obscura”.
But most of our respect should be paid to Giovanni Antonio Canaletto. As a painter he used the principle of the camera obscura in a very practical and commercial application. Although he did not take photographs as one understands it today, he imaged scenes and objects on canvas through a narrow hole in a curtain and painted them. With the help of this technique he was able to produce more than 900 paintings during his period. Later Giovanni Battista Della Porta suggested for the first time that a lens may be applied to the hole. This was the initial step for the invention of the portable “camera obscura” as a working tool for outlining at that time.
In the frame of this experiment a high performance industrial CCD zoom camera with USB computer connection is applied. Parameters like diaphragm size, position and the influence of lenses on the brightness, sharpness and dimensions of the image are investigated. The variable diaphragm demonstrates the effect of depth of field. Furthermore a LED emitting invisible radiation to the human eye is provided to study the exciting technology of active night vision.
