If so,
This bit of org-mode:
,----
| * headline
|
|
| #+BEGIN_SRC emacs-lisp :eval yes :exports both
| (defun test-filter-final (text back-end info)
| "What is back-end?"
| (concat "type-of back-end: "
| (format "%S" (type-of back-end))
| "\nname of back-end: "
| (symbol-name (org-export-backend-name back-end))))
|
| (add-to-list 'org-export-filter-final-output-functions 'test-filter-final)
| #+END_SRC
`----
will export via
C-c C-e l L y
as
,----
| type-of back-end: vector
| name of back-end: latex

Take a look at "(defstruct (org-export-backend..." in ox.el
