Holy crap - that's right, you've got the athermic windshield!!!!! angry
First, see if you can do the polarized sunglasses trick. See if you can't find some portion of your front glass which may not be treated. This may give your V1 at least its "forward vision" back.
You'll then need to see if any other of your greenhouse glasses are treated in this manner.
If you can't achieve good resolution this way, you've got two remaining choices:
(1) replace windshield (and other affected greenhouse glass) with non-athermic glass
-or-
(2) go with a remote-mounted detector
