This invention provides a single-degree-of-freedom deployable light shield to address the technical problem that existing rigid deployable light shields, with their columnar or planar configurations, are difficult to adapt to the obliquely tapered configuration required for large observation fields. The single-degree-of-freedom deployable light shield provided by this invention innovatively couples two sets of equivalent cranks and equivalent connecting rods connected by elastic drive hinges to a planar multi-stage scissor mechanism.
