5results about How to "Improve scan performance" patented technology

The embodiment of the invention relates to an optical scanner. The optical scanner comprises a polarizing beam splitter, a wave plate and an optical phased array chip. Wherein the polarizing beam splitter is used for dividing incident light source light into first laser with a first polarization state and non-working light with a second polarization state, reflecting the first laser and transmitting the non-working light, and the first polarization state is different from the second polarization state. The wave plate is located on the reflection light-emitting side of the polarizing beam splitter and used for receiving the first laser and emitting second laser with a third polarization state different from the first polarization state and the second polarization state. And the optical phased array chip is used for receiving the second laser and emitting reference light, and the optical phased array chip is also used for changing the emitting angle of the reference light. The embodiment of the invention further relates to a laser detection system with the optical scanner and an automatic driving vehicle applying the laser detection system.

The utility model provides a three-dimensional scanner with an adjustable scanning angle, which relates to the technical field of scanners and comprises a movable mechanism, the movable mechanism comprises a connecting column fixedly connected to one side of a support, the lower end of the connecting column is fixedly connected with a fixing block, the middle of the lower end of the fixing block is fixedly connected with a connecting block, and the lower end of the connecting block is movably connected with a ball. The outer wall of the lower end of the ball is fixedly connected with a connecting rod, the lower end of the connecting rod is fixedly connected with a sliding block, the lower end of the sliding block is fixedly connected with a scanning device, and one side of the fixing block is movably connected with a first transmission mechanism and a second transmission mechanism. According to the utility model, the problem that the scanning requirements of objects with complex shapes and diversified sizes are difficult to meet because the conventional scanners mostly adopt a fixed-angle or limited-angle scanning mode is solved. And the design of a fixed scanning angle is easy to cause a scanning blind area, so that part of key detail information is lost, and the precision and integrity of the model are influenced.

The utility model relates to the technical field of slide shooting, disclose a shooting anti shake mechanism of slide scanning imaging device, including the shell, the inner wall of shell is provided with stabilizing mechanism, the stabilizing mechanism includes the mounting panel, the inner wall fixed connection of mounting panel's outer wall and shell, the top of mounting panel both sides are all set up with a plurality of stable grooves, the inner wall sliding connection of stable groove has the sliding frame, the bottom both sides of sliding frame are all fixedly connected with a plurality of stabilizer bars, the outer wall sliding connection of stabilizer bar has the camera. In the utility model, the mounting panel is equipped with stable groove, and the threaded shaft one is rotated under the drive of servo motor one, makes the stable left and right sliding of sliding frame in stable groove, after servo motor two starts, threaded shaft two rotates, and the transmission camera slides on the stabilizer bar, and this structure ensures the stability and flexibility of scanning movement, reduces the shaking, improves the scanning effect.

This application relates to the field of office equipment technology, and more particularly to a paper feeding roller, a paper feeding mechanism, and office equipment. The paper feeding roller disclosed in this application is applied to a paper feeding mechanism and includes an outer ring portion and a shaft portion. The outer ring portion is sleeved on the shaft portion and protrudes from the outer peripheral surface of the shaft portion. At least a portion of the outer ring portion is configured to abut against the paper, wherein the length of the portion of the outer ring portion abutting against the paper along the axial direction of the shaft portion is 5 mm to 30 mm. By reducing the abutment length between the outer ring portion and the paper along the axial direction of the shaft portion, the pressure applied to the paper by the paper feeding roller in the paper feeding mechanism is more concentrated. When papers of different sizes enter the paper feeding mechanism, the paper feeding roller can ensure that the pressure is concentrated on the paper, especially in the middle of the paper along its width direction, thereby effectively avoiding the problem of paper skewing caused by the offset of the pressure application point.
