    Abstract: The objective of the present invention is to reduce the dispersion of a powdered substance, which is the target substance, during the analysis period in an analyzing device that analyzes the target substance by analyzing the light originated from the substance which is in the plasma state. The present invention relates to an analyzing device including a plasma generation means which generates plasma in the space and maintains plasma using the energy of EM radiation emitted from a radiation antenna; and an optical analysis means which analyzes a target substance by analyzing the plasma light generated from target substance of plasma state in the plasma area during the plasma maintenance period where the plasma is maintained by the plasma generation means using the energy of EM radiation. The plasma generation means emits the EM radiation from the radiation antenna in continuous waves during the plasma maintenance period.

    Abstract: The present disclosure relates to an optical sensing module, a system and a method for operating the optical sensing system. The optical sensing module includes a light emitter that emits a sensing light in a specific wavelength range and a photodiode unit. The photodiode unit includes a first photodiode used to sense a first wavelength light, a second photodiode used to sense a second wavelength light, and a third photodiode used to sense a third wavelength light. The optical sensing module implements a proximity sensor by operations of the second photodiode and the third photodiode, or a biometric sensor by operations of the first photodiode, the second photodiode, and the third photodiode. The photodiode unit receives a reflected light from an object to be detected so as to determine if the object is proximal, and then determine whether or not the proximal object is human skin.
