  In the last few years,the field of ghost imaging has seen many new
developments. From computational ghost imaging to 3D ghost imaging, this field
has shown many interesting applications. But the method of obtaining an image
in ghost imaging experiments still requires data to be recorded over long
duration of time due to averaging over many shots of data. We propose a method
to get the intensity correlated images in one shot by averaging over different
wavelength components rather than different time components.
