PROBLEM TO BE SOLVED: To provide an optical system capable of precisely grasping information by illuminating or displaying guidance information to object position information and an object position.SOLUTION: An optical system 100 includes an approach detection part 51 for detecting approach of an object to a prescribed area that is previously determined, a position detection part 52 for detecting a designation position for arranging the object, an optical device 1 for illuminating at least one between illumination light and display light, and a system control part 70 for making the optical device 1 radiate guidance information for guiding the object to the designation position detected by the position detection part 52 after the approach detection part 51 detects the approach of the object to the prescribed area that is previously determined.SELECTED DRAWING: Figure 2 |
