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.

Abstract: A multiple-lens camera system is provided, including a first lens driving module, a second lens driving module, and a shielding member. The first and second lens driving modules respectively include a frame, a lens holder movably disposed in the frame for holding a lens, a magnetic element disposed on a side of the lens holder and a driving board, wherein the driving board has a first coil corresponding to the magnetic element, to generate a magnetic force for moving the lens holder and the lens relative to the driving board. The shielding member is disposed in the first lens driving module and between the two magnetic elements of the first and second lens driving modules which are adjacent to each other, to suppress magnetic interference between the first and second lens driving modules.
