[0003] In the DMD projection system, the white light emitted by the light source is focused on the color wheel through a focusing lens, and the color wheel is mainly composed of a combination of red, green, and basket color light-emitting sheets, and the color filter is made by a high-speed motor. Rotate to separate the white light and then emit a specific color of light onto the DMD surface. The DMD surface consists of small mirrors corresponding to the number of pixels. These small mirrors rotate according to the control of the video signal. When the small mirror rotates until its reflected beam passes through the lens of the projector, it indicates that the pixel point is open. When the small mirror is rotated until its reflected beam is off the lens of the projector, it indicates that the pixel point is off, and the time of opening and closing is greater than the brightness of the pixel. When the red light hits the surface of the DMD, the lens on the DMD rotates the small mirrors on or off according to the red video signal, so that the reflected beam that needs to be displayed is projected onto the large screen through the lens of the projector, green and blue light and video. The signal is also working like this: The red, green and blue faces of the human vision system are collectively projected to see a full-color image. [0004] Please refer to FIG. 1 and FIG. 2, which are top and perspective views of an RGB tricolor color wheel 1〇. The color wheel 10 includes a three-color filter 1〇〇, a fixed portion 2〇〇, a motor 300 with 096130542, a form number A0101, a 4th page, a total of 22 pages, 1003128710-0, 1344056, a correction, a replacement page, and a paste on the fixed line. Timing Mark 400 of the side wall of the part 200. The trichromatic filter 100 includes a red filter 1〇2, a green filter 104, and a blue filter 106, all of which are fan-shaped and constitute a disc, wherein the human eye is red, green, and blue. The degree of color reaction is different. For example, the human eye is slow to respond to red, so the angles of the three color filters are usually not uniform 120 degrees, but the red wave first is larger. The three-color filter 100 is fixed to the fixed portion 2 by clamping or adhesive. The motor 300 drives the three-color filter 100 to rotate by driving the fixed portion 20 to rotate. The time stamp 400 is used to help the projector system recognize the position of the red filter 102, the green filter 1〇4, and the blue filter 106 in the current tri-color filter 100, that is, the video image projected at the moment. Like what color. The principle of color registration using the color wheel 10 is to achieve a visual persistence effect on the color by the human eye by the high speed rotation of the color wheel 10. It can be seen that in the color wheel 10 rotating at a high speed, the angles of the different color filters and the recognition of the current color of the color wheel I 投影 by the projection instrument directly affect the color quality of the image. If the color wheel 10 parameters do not meet the requirements, such as the angle of the red filter 102, the green filter 104, and the blue filter 106 of the three-color filter 100, and the time label 400 and the three-color filter. The relative position of the film 1 〇〇 is greatly deviated from the standard value, which will directly affect the color processing of the projector, resulting in image color confusion. [Invention] [0005] In view of this, it is necessary to provide a time to detect the color wheel.

[Embodiment] [0021] Please refer to FIG. 3, which is a structural diagram of a color wheel parameter detecting system 15 of a preferred embodiment for detecting The angle of the various color filters in the color wheel and the relative position of the time stamp to the tear wave plate. Due to the variety of color wheels, such as: three-color color wheel RGB; four-color color wheel RGB+W, where W is white; six-color color wheel RGBRGB, etc., the above-mentioned RGB and other colors all represent fan-shaped color filters, and some sectors The filter only has the outer ring portion as a color, and the plurality of fan-shaped color filters together constitute a disk. The following description will be made by taking the detection of the three-color color wheel 10 as an example.

Tricolor Filter 100 096130542 Form No. A0101 Page 8 of 22 1003128710-0 1344056 _ 100 April 15 Nuclear 1 Positive Replacement Page Includes Red Filter 1 02 'Green Filter 1 04 and Blue Color filter 106. The borders 120, 122, and 124 are formed adjacent to the red calender sheet 102, the green filter 104, and the blue filter 106 due to chromatic aberration. • [〇〇23] The color wheel parameter detecting system 15 includes a first sensor 20, a second sensor 30, and a processor 35. The first sensor 20 and the second sensor 30 are for emitting a light beam onto the color wheel 10 and receiving the light beam reflected from the color wheel 10, and generating a pulse signal according to the intensity change of the received light beam. [0024] The first sensor 20 is disposed opposite to the plane of the three color filter 100 for vertically transmitting the light beam onto the three color filter 100, and receiving the reflected light beam, according to the change of the reflected beam intensity. Pulse signal. Since the red filter 102' green filter 104 and blue filter 106 can only pass the light beams corresponding to their own colors, the reflected light beams are different. Therefore, when the emitted light beams pass through different color filters. When the boundaries between the light sheets are 120, 122, and 124, the intensity of the reflected beam changes. Thus, a pulse is generated. During the parameter detection process, the motor 300 drives the three-color filter 100 to rotate continuously and continuously, the first sensing. The device 20 generates a first pulse signal corresponding to the angles of the red filter 102, the green filter 104, and the blue filter 106. As shown in FIG. 4, the first pulse signal 40 is composed of three periodic boundary pulses 402, which represent between the red filter 102, the green filter 1〇4, and the blue filter 106. The three boundaries 120, 122, 124. [0025] The second sensor 30 is disposed on the side wall of the fixing portion 200 to which the time stamp 400 is attached, for vertically emitting a light beam to the side wall of the fixing portion 200 to which the time stamp 400 is pasted, and receives the reflection. The returning beam produces a pulse signal β according to the change of the reflected beam intensity. Because during the parameter detection process, 096130542 Form No. 1010101 Page 9/Total 22 Page 1003128710-0 «44056 100 April, 2014 Correction Replacement Page Motor 3〇〇 The τ moving fixed portion 2 〇〇 continuously rotates the second sensor. The beam emitted by the illuminator sometimes illuminates the side wall of the fixed portion 2 ,, sometimes illuminates the time stamp 4GG, and the reflected light intensity of the two is reflected. Differently, the second sensing benefit 3D is to generate a second pulse nickname according to the change of the reflected beam intensity. As shown in FIG. 4, the second pulse signal is composed of a periodically occurring time pulse 502. The processor 35 is configured to calculate a red filter 1〇2, a green filter 104, and a blue filter according to a time relationship between the first pulse signal 4() and the second pulse signal 50. An angle value of 1〇6, and an angle value formed by the time stamp 4〇〇 and the boundaries 120, 122, and 124. The angle formed by the time stamp 4〇〇 and the borders 120, 122, and 124: 3⁄4 is the sign of the sign in the radial direction of the trichromatic filter 100 and the i-boundary 12〇, 122 The angle formed by the '124' is the angle formed by the reflected beam on the time stamp 4 and the respective boundaries 120, 122, 124, and the a direction shown in FIG. 3 indicates the direction indicated by the time stamp 400. [0027] Referring again to FIG. 4, since the motor 300 is rotated at a constant speed, the time interval between any four consecutive pulses in the first pulse signal 40 is the rotation period, that is, 360 degrees. If the area indicated by the frame 450 indicates a rotation period, the time proportional relationship of the three intervals between the four pulses indicates the angles of the red filter 102, the green filter ι 4 and the blue filter 106. The ratio, based on a total of 360 degrees, can be obtained as the angle value of the red filter 1 0 2, the green filter 1 0 4 and the blue filter 1 〇6. Similarly, according to the time difference between the time pulse 5 〇2 in the first pulse nickname 50 and the boundary pulse 4 0 2 in the same period, the angle value of the time label 4 〇〇 and the boundaries 120, 122, 124 can be calculated. . 096130542 Form No. 1010101 Page 10/Total 22 Page 1003128710-0 1344056 _ 100 April 15th Nuclear Replacement Page [0028] The above color wheel parameter detection system 15 is rotated by the color wheel 1〇 by the first The sensor 20 and the second sensor 30 emit a light beam onto the color wheel 1 并 and receive the reflected light beam 'to generate a first pulse signal 40 and a second pulse signal 5 对应 corresponding to the parameters of the color wheel 1 〇, and The angle values of the red filter 1 〇 2, the green filter 104, and the blue filter 1 〇 6 and the time label 4 〇〇 and the boundaries 120 and 122 are obtained according to the time interval relationship of each pulse in the two pulse signals. The angle value of 124 can be compared with the standard angle value according to the calculated angle value to determine whether the color wheel 1 符合 meets the requirements. Referring to FIG. 5, an architectural diagram of a color wheel parameter detecting system 25 of another preferred embodiment includes a third sensor 60, a mirror 7A, and a processor 65. The second sensor 60 is disposed opposite to the plane of the dichroic filter 1 , for vertically emitting the light beam onto the tri-color filter 100, and receiving the return beam, and generating a third according to the change of the return beam intensity. Pulse signal. The mirror 7 is disposed on the side of the three-color filter 100 facing the time stamp 4 〇 , and at an angle of 45 degrees to the three-color filter 100. The mirror 70 is for reflecting the light beam emitted from the third sensor 60 and passing through the three-color filter 1A onto the side wall of the fixing portion 200 to which the time stamp 400 is attached. Wherein, the position of the mirror 7〇 varies with the angle of the incident light, and only the beam needs to be reflected to the desired position. During the parameter detection process, the motor 3 〇〇 drives the fixed portion 200 to continuously rotate. When the emitted light beam passes through the three boundaries 12〇, 122, and 124, the intensity of the returned light beam is obviously different, and the third sensor 6 generates a boundary accordingly. Pulse, when the light beam reflected by the mirror 70 passes the time stamp 400, since the side wall of the fixing portion 200 is different from the time stamp of the time stamp 4', the returned light intensity is different, that is, the third sensor receives 096130542 form number.

Please refer to FIG. 6 , which is a third pulse signal 8 产生 generated by the third sensor 60. Any five consecutive pulse intervals in the second pulse signal 80 represent a rotation period, that is, 360 degrees. For example, a rotation period is indicated between the frame areas of the indication frame 8〇6 because the amount of change in the intensity of the return light when passing through the boundaries 12〇, 122, and 124 is different from the amount of change in the return beam intensity when passing the time label 4〇〇. Moreover, the positional relationship between the time stamp 4〇〇 and the three-color filter 1〇〇 is fixed, so that the amount of change in the return beam intensity is the same every time the time label 4 经过 passes, so a simple test can be distinguished. The boundary pulse and the nickname in the third pulse signal 80 are 8〇4.
