Abstract:
A sensing method includes sensing the target object by sensing light that is derived from emitted light and has passed the target object, in which the emitted light is circularly polarized light, sensed light is circularly polarized light, and light derived from the emitted light is incident to the target object at an angle greater than 20° and equal to or smaller than 70° that is formed with a normal line of the target object.
