Abstract: A modeling system is provided, including a light-emitting source, a chromatic aberration member, and a receiving module. The light-emitting source can emit a mixed light, including a main light having a first wavelength and a sub-light having a second wavelength. The main light and the sub-light are emitted along an emission path and toward an object, and they are reflected by the object after reaching it. The chromatic aberration member is disposed on the emission path. The receiving module includes a main body, a receiving member, a space filtering member, and a first driving assembly. The receiving member is disposed on the main body. After being reflected, the main light and the sub-light move along a reflecting path and reach the receiving member. The space filtering member is disposed on the reflecting path. The first driving assembly can drive the space filtering member to move.

Abstract: A distance measuring device for measuring the distance to an object is provided, including a light-emitting module, a driving assembly disposed in the light-emitting module, and a light-receiving module. The light-emitting module has a housing, a light source disposed in the housing, a light grating element, and an optical path adjuster. The light source emits a measuring light sequentially through the optical path adjuster and the light grating element along a first axis. The driving assembly can drive the optical path adjuster or the light grating element to move relative to the housing. The light-receiving module receives the measuring light which is reflected by the object to obtain distance information of the object.
