Abstract
A tilt detector and tilt detecting method for the same are disclosed. The tilt detector includes a light-detecting unit and a light-permeable unit. The light-detecting unit includes a body, a window formed on the body, and a signal port device formed on the body. The window detects the position of a moving facula, and the signal port device outputs the facula location signal. The light-permeable unit mounted in the window and includes a chamber, an opaque fluid filled with the chamber, and a light-permeable substance formed on the opaque fluid. The window detects a facula by the light-detecting unit when a beam is emitted to the window via the light-permeable substance. Therefore, the level of a subject is detected by observing the light-permeable substance directly, and obtains the precise level by the signal outputted from the signal port device.
