Solid-state blue laser pointer are generally small and robust, with high pulse radiation power and a wide range of applications. Nd:YAG laser. Nd (neodymium) is a rare earth element, YAG stands for yttrium aluminum garnet, and its crystal structure is similar to ruby. Good directionality; good monochromaticity; energy concentration; good coherence. X-ray lasers are of great value in scientific research and military affairs, and they have advantages when used in laser anti-missile weapons. Biologists can use X-ray lasers to study the molecular structure of living tissues or understand cell functions in detail; use X-ray lasers to photograph molecular structures. In the photo, the contrast of the obtained biomolecule image is very high. Chemical lasers Some chemical reactions produce enough high-energy atoms to release large amounts of energy, which can be used to produce laser action.

There are many ways to classify lasers. For example, it can be classified according to the material it cuts, it can be divided according to its power, and it can be divided according to waveband. According to the waveband, laser equipment can be divided into visible light, infrared, ultraviolet, X-ray, and multiple wavelengths. Tuning, the current industrial use of infrared and ultraviolet lasers. For example, CO2 laser 10.64um infrared laser, krypton lamp pumped YAG laser 1.064um infrared laser, xenon lamp pumped YAG laser 1.064um infrared laser, semiconductor side pumped YAG laser 1.064um infrared laser.

When operating a forestry machine wirelessly from a remote location, the operator operates the machine while watching the image of the camera installed on the machine. However, if you only rely on camera images to operate the machine, you will lose the machine's own angle of view and posture and other information, thereby reducing operability. Therefore, in this research, the relative positional relationship between the machine and the workpiece and the workpiece is based on the camera image. The purpose is to supplement the missing information and provide the operator with useful information for the operation of the machine. We have developed a device that automatically measures size and shape.

The laser pointer is mounted on a rotating table with two rotating shafts so that the operator can irradiate the laser in any direction. Rotary encoders are installed on each rotating shaft and can measure the angle of rotation. The linear Laser pointer can be specified according to the rotation angle of each axis.

In order to clarify the measurement accuracy of the device, a three-dimensional position measurement test of the object was carried out. In the test, the distance between the camera and the high power laser pointer (baseline length) is set to three stages of 1.0m, 1.5m, and 2.0m, and the accuracy of the position of the object from 2.0m to 10.0m is measured to verify the accuracy. went. As a result, as the measurement distance becomes longer, the accuracy of the measurement decreases, while in long-distance measurement, as the length of the baseline becomes longer, the accuracy increases. However, the results show that at very close distances from the measuring equipment, the difference due to the baseline length is small (Figure 4). In summary, when this equipment is used for such forestry machinery with a working range of 2.0 m to 6.0 m, setting the baseline length between 1.5 m and 2.0 m can improve the measurement accuracy. Fixed within l cm. It can be said that this is sufficient accuracy for operating the working machine. In addition, Figure 5 shows the workpiece scanned with this device and the result output on the screen. In this way, information such as the size and shape and location of the workpiece can be provided to the operator.

An overview of the laser?

Laser Light is emitted from the atoms that make up matter. After the atoms gain energy, they are in an unstable state (that is, excited state). It emits energy in the form of photons. The high power laser pointer is a photon queue that is lured (excited). The photons in this photon queue have the same optical characteristics and extremely consistent pace. An analogy is that ordinary light sources, such as light bulbs, emit different photons, and they will run around in all directions, which is not united. However, the photons in the laser are thinking about one place and moving toward one place. This leads to They are so invincible and powerful that people used to call lasers "dead light".

An overview of infrared light?

Infrared (Infrared) is an electromagnetic wave with a wavelength between microwave and visible light. The wavelength is between 760 nanometers (nm) and 1 millimeter (mm), which is invisible light that is longer than red light. Any substance above absolute zero (-273.15°C) can produce infrared rays. Modern physics calls it heat rays. Medical infrared can be divided into two categories: near infrared and far infrared. Containing heat energy, the heat of the sun is mainly transmitted to the earth through infrared rays.

Lasers also work in the infrared band. Green laser pointer can be understood as a form of light source, and infrared refers to a specific waveband of electromagnetic waves (although the range is large). The non-homogeneous differences between them will not prevent them from intersecting. The visible light waveband laser allows everyone to have This is a preconceived concept. . It's actually
