ELECTRO OPTICAL MODULATOR, ELECTRO OPTICAL SENSOR, AND DETECTING METHOD THEREOF

摘要

The disclosure relates to an electro optical sensor, which comprises a light source generating device, an electro optical modulator, a supporting module, and an image capturing module. The light source generating device emits a light beam. After the electro optical modulator modulates the light beam, the modulated light beam emits onto a subject. The supporting module includes a transparent substrate, supporting the subject and allowing the modulated light beam to incidentally emit into the transparent substrate. The image capturing module converts the light beam reflected from the supporting module into a video signal.
