The light irradiation module 100 is a functional module for irradiating the laser beam toward the target T. The light receiving module 200 receives at least a part of the light generated by the laser beam irradiated on the target T .

Herein, "light generated by a laser beam irradiated on a target" (hereinafter, simply referred to as "generated light") may mean any kind of light generated when a laser beam is irradiated onto a target, Reflected light, scattered light, plasma light, and fluorescent light. The light receiving module 200 can receive at least a part of the generated light as 'received light'.
