Title:
RANGE SENSING SYSTEM
Document Type and Number:
WIPO Patent Application WO2004090568
Kind Code:
B1
Abstract:
The invention relates to a range sensing system. An energy source is adapted to emit energy which is capable of reflection by a target. The energy source is activated and deactivated in a cyclic pattern with a selected source frequency. A receiver is adapted to sense the reflection of emitted energy from the target. The receiver includes a shielding system to block the sensing of reflected energy from the target in a cyclic pattern with a selected receiver frequency. The output signal of the receiver is compared with a reference signal whereby the phase differences between the receiver signal and reference signal is used to determine a range value.
