| 摘要 |
This optical system (1) for three-dimensional imaging is provided with: a first optical system (G1) that has, in order from object side to imaging side, at least a negative lens and an aperture (S), the first optical system (G1) having rotational symmetry around a first central axis (C1); a second optical system (G2) that has rotational symmetry around a second central axis (C2) parallel to the first central axis (C1), the second optical system (G2) having the same structure as the first optical system (G1) and being arranged parallel thereto; and a variable optical system (Gv) disposed so as to intersect with the respective light paths of the first optical system (G1) and the second optical system (G2); the variable optical system (Gv) having at least one variable optical element in which the focus and/or the convergence can be changed. |
