<p>PROBLEM TO BE SOLVED: To accurately acquire information of an object with a compact configuration.SOLUTION: An imaging apparatus includes at least one lens 131 having a cylindrical surface or an anamorphic surface, a sheet beam generation optical system 103 for shaping light from a laser source 120 to sheet-like light, and an imaging optical system 150 for condensing Raman scattered light RSL generated by irradiating the sheet-like light on an object. An optical axis OA1 of the sheet beam generation optical system and an optical axis OA2 of the imaging optical system 150 are parallel to each other.</p> |
