Have you heard of lidar?
This powerful laser pointer is very similar to an LED (Light Emitting Diode) flashlight. Is it really that powerful? Reviewer experience: The powerful laser pointer rotates to make light emerge from the focal point. At a distance of six inches from the high powered laser pointer, the reviewer carefully moved the match head toward the laser beam, only to hear a "pop", and the match ignited instantly. By knowing the position and direction of the sensor, the XYZ coordinates of the reflecting surface can be calculated and represented by a point.

By repeating this process over and over again, the instrument constructs a complex "map" consisting of all the points collected by LiDAR. The figure below explains how waves are refracted on the surface. Part of the wave is reflected at the same angle of incidence (specular reflection), another part is refracted by the surface, and the last part is diffusely reflected at a different angle of incidence. The main difference in using a laser pointer as a chasing toy is that your dog will never reach the goal of catching it. This means that the reward is always in pursuit of the blue laser pointer, but your dog will never be able to catch it. This can cause serious confusion for your dog. The main problem is that, physiologically, your dog never really finds the end in achieving the goal, which can lead to unhealthy obsessions and behavioral problems. Some dogs may be so obsessed with moving the red pointer that they start chasing anything that moves, such as shadows, glare, or glare from swimming pools or tablet screens.
