In particular, when the shadowless lamp has polarized light or uneven lighting effects, these devices are often unable to perform effective detection. This limitation not only affects the accurate evaluation of the performance of the shadowless lamp, but may also lead to risks caused by insufficient or uneven lighting during surgery.
