Spatial Light Modulator to remove high intensity light

[cyber stealth]

Is there a way to use a Spatial Light Modulator or other device to remove high intensity light without removing low intensity (low amplitude) light from a physical object you are observing?

High intensity light would be completely filtered (removed) but low amplitude waves would not be removed.

I considered using a half-silvered mirror to reflect part of waves and use destructive interference but I could not come up with a way to destructively interfere with only the high-amplitude waves.

Note, dark "sunglasses" would not work because they attenuate both high intensity and low intensity light waves.

Do you mean something like a DC stop?

These guys use something fancy:

but a small dot of white-out is sufficient to block the central peak.
