.. py:function:: projectorconstructor(target_geo: vamtoolbox.geometry.TargetGeometry, proj_geo: vamtoolbox.geometry.ProjectionGeometry, optical_params=None)

   Constructor to create the projector based on the target size and projector type selected

   :param target_geo:
   :type target_geo: geometry.TargetGeometry
   :param proj_geo:
   :type proj_geo: geometry.ProjectionGeometry

   :returns: the projector object has methods forward() and backward()
   :rtype: Projector object

   .. rubric:: Examples

   >>> A = projectorconstructor(target_geo, proj_geo)
   >>> b = A.forward(x) # returns the forward projection (sinogram)
   >>> x_ = A.backward(b) # returns the backward projection (reconstruction)
