pinhole camera

21:32  , , , , ,  No comments

Pinhole camera is based on the principle that light travels in a straight line 

 Construction
 A pinhole camera consists of a cardboard or wooden box having a pinhole in its front face and a translucent grounded glass/waxed paper screen at the back.the distance between the pinhole and the screen may be the fixed or adjustable.the distance between the pinhole and the screen can be adjusted by moving the screen towards or away from the pinhole

     Working :When the pinhole of the camera is turned towards a bright object,a real,inverted image of the object is formed on the screen.the nature has provided you a large number of pinhole cameras.you have to simply stand under a dense tree on a sunny day and watch the round patches of light on the ground.these round patches are the images of the sun.the gaps between the leaves are the pinholes.
Advantages of Pinhole Camera
    A pinhole camera has the following advantages.
         *No focusing is required.
         *There is no lens in pinhole camera.therefore,the image is free from spherical and chromatic aberrations.
Disadvantages of Pinhole Camera
     A pinhole camera has the following disadvantages.
         *The image formed does not give any details.usually,the image is hazy.
         *Image is obtained on the screen.No permanent record of the image can be obtained.
         *Pinhole camera cannot be used for studying moving object.
