4
Methods The Experimental Set Up
Reflected Light is detected by photo-resistors
Light exiting the pinhole is reflected by the
object plane
5
The Methods Set Up
Incoherent Light Source.
6
The Methods Set Up
Control Background used to minimize refection due
to object stand.
7
The Methods Set Up
Photo-resistors used to detect an calculate the
relative intensity of reflected light.

Methods
Assuming 570 nm for the wavelength of the light,
the coherence area of the source can be
approximated using equation 5.6-12 from Goodman
