On the Level

摘要

Peering through binoculars can make an impossibly faraway object look close enough to touch, but with a trade-off: Any little jostle can knock a view out of frame. Most consumer binoculars have a built-in image-stabilization system that uses an accelerometer, a processor, and a small motor to compensate for user movements. But that system only offsets slight jolts, and the processing time required creates a several-millisecond lag.
