Detection device and detection method

Abstract

A detection device includes a signal generator, an FSS (Frequency Selective Surface), an EO (Electro-Optical) crystal element, a light source, a light waveguide, a light sensor, and a processor. The signal generator generates an mmWave (Millimeter Wave) signal. The EO crystal element is adjacent to the FSS. The mmWave signal is transmitted through the FSS and the EO crystal element to a human body portion. The human body portion transmits a reflection signal back to the EO crystal element. The light source generates a light communication signal. The light waveguide is adjacent to the EO crystal element. The light waveguide transmits the light communication signal. The light communication signal is modulated according to the reflection signal. The light sensor receives the light communication signal from the light waveguide. The processor can analyze the light communication signal, so as to obtain the physiological information of the human body portion.
