Abstract: An optical environment oscillation detection system and an optical measurement method using the same are provided. This system includes a laser light source, a polarizer, a liquid crystal (LC) element, an analyzer, and an optical sensor arranged in sequence. A polarization axis of the polarizer and that of the analyzer are respectively parallel to a first and a second axis direction being perpendicular to each other. When there is no environmental disturbance, the alignment of LC cells in the LC element has an original pretilt angle, and the optical sensor senses a first scattered light intensity of the laser beam outputted from the analyzer. When there is environmental disturbance, the alignment of the LC cells has a changed pretilt angle in relative to the original pretilt angle, and the optical sensor senses a second scattered light intensity of the laser beam outputted from the analyzer.
