Detailed Description
The following describes a modeling system and a modeling method of an embodiment of the present invention. It should be appreciated, however, that the present embodiments provide many suitable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.
Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Referring to fig. 1, a modeling system 10 according to an embodiment of the invention mainly includes a light emitting source 100, a light path control module 200, a color element 300, a color element driving assembly 400, a switchable filter element 500, and a receiving module 600.
The light emitting source 100 may emit a composite light L, and the composite light L may include a main light L1 having a first wavelength, a sub-light L2 having a second wavelength, and another sub-light L3 having a third wavelength. For example, the composite light L may be a white light, and the main light L1, the sub light L2, and the sub light L3 may be a green light with a wavelength of 550nm, a red light with a wavelength of 650nm, and a blue light with a wavelength of 400nm, respectively. The composite light L may also include more light rays with different wavelengths, and in some embodiments, the composite light L may include 420 to 600 light rays with different wavelengths.
The optical path control module 200 is disposed between the light source 100 and the chromatic aberration element 300, and when a user uses the modeling system 10 to obtain the profile of an object B, the chromatic aberration element 300 is located between the light source 100 and the object B.
The optical path control module 200 can be, for example, a half mirror, and the reflecting surface 210 faces the chromatic aberration element 300, so that the composite light L provided by the light emitting source 100 can directly pass through the optical path control module 200 along an emission path P1 to reach the chromatic aberration element 300. When the composite light L passes through the chromatic aberration element 300, the main light L1, the sub light L2, and the sub light L3 are focused on different planes, respectively, due to the different wavelengths. Therefore, when the composite light L is emitted to the object B along the emitting path P1, only the surfaces at the distances corresponding to the focal lengths of the light rays (the main light ray L1, the sub-light ray L2, and the sub-light ray L3) will completely reflect the light rays, i.e., the intensity of the reflected light rays is approximately equal to the intensity of the light rays before reflection.
For example, the main light ray L1, the sub-light ray L2, and the sub-light ray L3 passing through the chromatic aberration element 300 may be focused on the surfaces B1, B2, and B3 of the object B, respectively. Therefore, the surface B1 can completely reflect the main light ray L1, and the sub-light rays L2 and L3 cannot be completely reflected by the surface B1 or the surface B1. Similarly, the surface B2 can completely reflect the secondary light ray L2, and the primary light ray L1 and the secondary light ray L3 cannot be reflected by the surface B2 or cannot be completely reflected by the surface B2; the surface B3 can completely reflect the secondary light ray L3, and the primary light ray L1 and the secondary light ray L2 cannot be completely reflected by the surface B3 or the surface B3.
The chromatic aberration element driving assembly 400 can be connected to the chromatic aberration element 300 to drive the chromatic aberration element 300 to move along the X-axis direction and/or the Y-axis direction relative to the light emitting source 100, so as to adjust the focus positions of the main light L1, the sub light L2 and the sub light L3.
In the present embodiment, the chromatic aberration element driving assembly 400 includes an electromagnetic driving element 410 and an electromagnetic driving element 420, the electromagnetic driving element 410 is disposed on the chromatic aberration element 300, and the electromagnetic driving element 420 is fixed with respect to the light emitting source 100. The electromagnetic driving element 410 may be a coil, and the electromagnetic driving element 420 may include a magnetic element (e.g., a magnet), such that when a current is applied to the coil (the electromagnetic driving element 410), an electromagnetic action generated between the coil and the magnetic element may move the chromatic aberration element 300 relative to the light emitting source 100. In some embodiments, the electromagnetic driving element 410 may be a magnetic element, and the electromagnetic driving element 420 may be a coil.
Referring to fig. 2, the reflected main light L1, sub light L2 and sub light L3 can move to the receiving module 600 along a reflection path P2. During the movement, the main light beam L1, the sub light beam L2 and the sub light beam L3 first pass through the color difference element 300 again, then are reflected by the reflective surface 210 of the light path control module 200, pass through the switchable filter element 500 and then proceed toward the receiving module 600.
The switchable filter element 500 includes a plurality of switchable filters, so that when the main light beam L1, the sub light beam L2, and the sub light beam L3 pass through the switchable filter element 500, only a single wavelength of light will pass (the main light beam L1, the sub light beam L2, or the sub light beam L3). In addition, the switchable filter element 500 can rapidly switch different filters, so that different light beams can enter the receiving module 600 in a short time.
As shown in fig. 3 and 4, in some embodiments of the invention, the position of the switchable filter element 500 may be changed according to the requirement. For example, the switchable filter element 500 may be disposed between the light source 100 and the optical path control module 200 (fig. 3), or disposed between the optical path control module 200 and the chromatic aberration element 300 (fig. 4). In some embodiments, the modeling system 10 may also include a plurality of switchable filter elements 500.
Referring back to fig. 2, the receiving module 600 includes a body 610, a receiving element 620, a spatial filter element 630, a first driving element 640, and a second driving element 650. The main body 610 may be a box body, which is opened only at one end facing the optical path control module 200, so as to allow the main light L1, the sub light L2, or the sub light L3 to enter. The receiving element 620 and the spatial filter element 630 are disposed in the box body, wherein the receiving element 620 is configured to receive the main light L1, the sub light L2 and the sub light L3, and the spatial filter element 630 is located between the optical path control module 200 and the receiving element 620.
The receiving element 620 may include a photosensitive element, and the spatial filter element 630 may be a pinhole (pinhole). When the main light beam L1, the sub-light beam L2, or the sub-light beam L3 passes through the spatial filter 630, the high frequency noise in the light beam can be filtered, so that the receiving device 620 can obtain more clear signal information after receiving the light beam.
It should be noted that the spatial filter element 630 should be disposed at the focal point of the main light ray L1, the sub light ray L2, and the sub light ray L3 reflected by the reflection surface 210. The aforementioned first and second driving assemblies 640 and 650 may connect the body 610 and the spatial filter element 630 to provide a driving force to move the spatial filter element 630 relative to the body 610.
In this embodiment, the first driving assembly 640 includes an electromagnetic driving element 641 and an electromagnetic driving element 642, which are respectively disposed on the body 610 and the spatial filter element 630 and correspond to each other. The electromagnetic driving element 641 may be a magnetic element (e.g., a magnet), and the electromagnetic driving element 642 may be a coil. When a current is applied to the electromagnetic driving element 642, the electromagnetic action between the electromagnetic driving element 641 and the electromagnetic driving element 642 can generate a driving force, so that the spatial filter element 630 moves along the X-axis direction (the first direction) relative to the body 610. In some embodiments, the electromagnetic driving element 641 may be a coil, and the electromagnetic driving element 642 may be a magnetic element.
The second driving assembly 650 includes an electromagnetic driving element 651 and an electromagnetic driving element 652, which are respectively disposed on the body 610 and the spatial filter element 630 and correspond to each other. The electromagnetic driving element 651 is a magnetic element (e.g., a magnet), and the electromagnetic driving element 652 is a coil plate. When a current is applied to the electromagnetic driving element 652, the electromagnetic action between the electromagnetic driving element 651 and the electromagnetic driving element 652 can generate a driving force, so that the spatial filter element 630 moves along the Y-axis direction and/or the Z-axis direction (second direction) relative to the body 610. In some embodiments, the electromagnetic driving element 651 may be a coil plate, and the electromagnetic driving element 652 may be a magnetic element.
In some embodiments, the first driving assembly 640 includes at least two electromagnetic driving elements 641 and at least two electromagnetic driving elements 642. At least two electromagnetic driving elements 642 are disposed on opposite sides of the spatial filter element 630, and the electromagnetic driving element 641 is correspondingly disposed on the body 610. By causing currents of different magnitudes to flow into the electromagnetic driving element 642 (or the electromagnetic driving element 641) on the opposite side, different driving forces can be generated on the opposite side of the spatial filter element 630, so as to drive the spatial filter element 630 to rotate around a rotation axis R.
The main light L1, the sub-light L2 and the sub-light L3 pass through the spatial filter 630 and then can be received by the receiver 620, and the receiver 620 then calculates the profile of the object B according to the received signal information.
Referring to the drawings, first, a user can provide the modeling system 10 as shown in any one of fig. 1, 3 and 4, and make the light emitting source 100 emit a composite light L toward the object B.
The composite light L passing through the chromatic aberration element 300 is separated into a main light L1, a sub-light L2, and a sub-light L3. The main light L1, the sub light L2, and the sub light L3 are reflected after contacting the surface of the object B, and the reflected main light L1, the sub light L2, and the sub light L3 are reflected to the receiving module 600 by the reflection surface 210 of the optical path control module 200.
At this time, the user can adjust the position of the spatial filter element 630 by using the first driving assembly 640 and the second driving assembly 650, so that the spatial filter element 630 is located at the focal point of the main light ray L1 (usually, the focal point of the sub light ray L2/the focal point of the sub light ray L3). Then, the main light ray L1, the sub light ray L2, and the sub light ray L3 are received by the receiving element 620.
In the present embodiment, the switchable filter element 500 can rapidly switch different filters, so that the receiving element 620 sequentially receives the main light L1, the sub-light L2 and the sub-light L3 in a short time. In some embodiments, the receiving element 620 can process light with different wavelengths simultaneously, so the switchable filter element 500 can be omitted to receive the main light L1, the sub-light L2 and the sub-light L3 simultaneously.
Finally, the receiving element 620 can calculate the profile of the object B by comparing the principal ray L1, the sub-ray L2, and the sub-ray L3. In detail, the receiving device 620 can construct an initial plane through the signal information of the main light beam L1, and calculate the profile of the object B according to the focal distance between the main light beam L1 and the sub-light beam L2/the sub-light beam L3, and the signal information of the sub-light beam L2/the sub-light beam L3.
In some embodiments, the modeling system 10 may further include an inertia sensing element for sensing the gravity state of the modeling system 10 and a control element (not shown) electrically connected to the inertia sensing element and the first driving assembly 640 and the second driving assembly 650. The control element may control the first driving component 640 and/or the second driving component 650 to drive the spatial filtering element 630 to move according to the gravity state measured by the inertial sensing element.
In summary, the present invention provides a modeling system, which includes a light emitting source, a color difference element, and a receiving module. The light emitting source can emit composite light, wherein the composite light comprises a main light with a first wavelength and a sub light with a second wavelength. The main light ray and the secondary light ray are emitted to an object along an emission path and reflected by the object after arriving. The chromatic aberration element is arranged on the emission path. The receiving module comprises a body, a receiving element, a spatial filter element and a first driving assembly. The receiving element is arranged on the body, and the main light ray and the auxiliary light ray reach the receiving element along a reflection path after being reflected by the object.
