New description: [New technical field] 〃本作铩 The optical structure of a laser input device, especially an optical input device with a beam splitter, so that the reflected laser 2 is split by the beam The device respectively reflects two axial beams of the same frequency and intersecting, and images the interference fringe pattern at the parent of the axial beam, and senses the change of the interference fringe pattern to further interpret the input device; The direction of displacement and the distance of the displacement have been judged - in the Zhuangli... The class achieves a sensitive and accurate calculation of the direction and distance of the I input displacement. [Prior Art] According to the advancement and development of science and technology, computers have become an indispensable part of human beings, and the wheel and/or equipment are equipped with keyboards for computers, computer keyboards, etc. Etc.) is also constantly updating the research and development to replace the bulky keyboard «controllable", the mouse has an irreplaceable ^/. The media and the Internet are currently selling the mouse-and-mouse mouse and optical mouse on the market. The mechanical slippery air can be divided into the ball on the =, using the mobile mouse to make the track __要# The sensing component in the mouse, the advantage of the mechanical ball in the mouse is the distance of the mechanical door. The distance of the mouse is easy to numb in the process of rolling. However, the shortcoming is that the object is brought into the interior of the mouse and gradually becomes tired: it is easy to accumulate dust and dirt on the table. After long-term use, it will accumulate to a certain range of M306693 degrees. The effect of the mechanical slippery 13⁄4 use time increases and the accuracy is reduced. Stupid #The technical principle of the mouse is in the 轸 _ ink pot source (usually __ hiding) to illuminate the target surface for a certain period of time撷 俸 俸 俸 俸 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' The aforementioned mechanical mouse is prone to wear and dust, but its disadvantages The result is relatively complicated, which results in a relatively high manufacturing cost. Since the response speed of the optical mouse depends on the accuracy of the image captured by the mouse, the light beam reflected from the target surface is in addition to the pixel size of the light-sensing benefit. Whether it can be properly captured by the light sensor, but also affects the accuracy. Therefore, the optical mouse that can achieve the more appropriate reflected beam is better. The accuracy is also good. An optical mouse, such as the optical slider structure modified by the patent No. 245538, has a light source (light guiding projection element) for emitting a light beam and a photo sensor (image sensing element). composition. Wherein the light sensor is directed downward to the target surface and obliquely cuts the light reflection path of the light beam, so that when the reflected light beam passes through the light reflection path, it is tangent to the light sensor. The light sensor is taken through the beam and analyzed for image. When the light source (light-guiding projection element) is projected onto the target surface, light and shadow of different sizes are generated, and the image is continuously captured by the light sensor (image sensing element) to sense the movement of the mouse on the target surface. Causes the difference in the fixed point on the target surface illuminated by the beam, reflects the difference of M306693 light east and uses the buried component at the back end signal to accurately calculate the distance and direction of the mouse movement. In the description, it can be found that the optical mouse can accurately calculate the distance and direction of the displacement of the mouse, and the projection of the illumination source generated by the light source is absolutely related to whether the light and shadow of different sizes are bright and good on the working table. - However, as described above, since the light beam is reflected from the target surface, there is a serious astigmatism phenomenon. When the light sensor reflects light on the target surface, the light beam is worn out and insufficient, resulting in insufficient image analysis data. It is impossible to accurately calculate the distance and direction of the mouse displacement, so that the mouse cursor displays the beating and partial wire condition, which leads to the improvement of the optical mouse money recording and the ease of use. In view of the above-mentioned lack of practical application of the optical mouse, and the accumulation of personal experience in the relevant industry development practice, the creators of the present case finally developed an optical structure of a laser input device: Content] The main purpose of this creation is to provide a laser input device light =,,. The laser beam is used as a light source, and the reflected laser beam is respectively reflected by the beam splitter to two intersections of the same frequency and intersecting beams of light, which are adjacent to the two axial beams. The imaging light interference fringe pattern is taken, and the displacement direction and the displacement distance of the input device surface are further interpreted by sensing the change of the interference fringe pattern (4), and the direction and distance of the displacement of the input device are determined by the sensitive and precise calculation. In order to achieve the above object, the present invention provides an optical structure of a laser input device M306693, which comprises: an input device body; and a device for providing a straight line projection: a light Α „./〇: ΐ ΐ a first interface sounding and a second interface at the rear end of the first interface, and the first interface and the second interface are respectively located on the light reflection path of the laser beam, so that the first interface and the first interface The second interface respectively reflects an axial beam having the same frequency and t mesh intersection; a photo sensor is located at the parent g of the biaxial beam to sense the optical interference imaged by the axial beam intersection According to the above configuration, when the input device body moves, the change of the optical interference fringe pattern is read by the photo sensor, and the displacement direction and the displacement distance data of the input device body are determined correspondingly.

According to the first figure, the first 'Yuer is: sticky, because the input device body 1'' the fixed slot 3 1 correspondingly accommodates the laser light source 2 and the lens holder 3 top ^ The photo sensor 5 is disposed corresponding to the recessed portion 32, so that the relative positions of the laser light source 2 and the photo sensor 5 are fixed and easy to position. When the operation is started, the laser beam a projected by the laser light source 2 is transmitted through the first lens 3 3 of the lens holder 3 to the working surface 6 along an incident path of an incident angle of 25 to 45 degrees. The light beam a is blocked by the working surface 6 and reflected to form a reflected light beam b projected onto the first interface 4 1 of the beam splitter 4 on the reflective path.
