According to the performance characteristics of the night vision camera itself, wearing it will generally have the following physiological and psychological effects on the user. So what are the physical and psychological effects of wearing a night vision camera? Let's take a look at it next.
Here is the content list:
The brain needs to reinterpret image signals
Inability to adapt to distance
FOV is too small
Loss of proprioception and balance
Different from the colorful images common to the naked eye, the imaging of the night vision camera is an image composed of different color levels of monochrome (divided into green, yellow-green, and gray according to the different screen materials). Time adaptation, in the initial period of wearing the night vision camera, if you directly perform high-dynamic training, it will lead to headaches and acceleration of human metabolism.
Humans create a sense of three-dimensionality and distance through the different axes of the eyes. Failure to grasp the correct sense of distance will lead to the inability to accurately position oneself during the action and may collide with surrounding objects, fail to accurately use cover, fail to catch or avoid flying objects, etc., which will seriously affect law enforcement safety.
In an optical instrument, the angle formed by the lens of the optical instrument as the vertex and the angle formed by the two edges of the maximum range of the object image of the object to be measured can pass through the lens is called the field of view. The larger the field of view, the larger the field of view in the optical instrument. Even the four-eye night vision device has a field of view of 97 degrees, which is far smaller than the field of view of the naked eye, which is 120 degrees, while the night vision camera equipped with general special police units has a field of view of only about 40 degrees, without adaptation. Training cannot complete dynamic shooting or other tactical behaviors, especially in room search operations, where scans of the surrounding environment are missing, creating a law enforcement risk. Another thing that is easily overlooked is that the field of view is not only in the horizontal direction but also in the vertical direction. The field of view of the night vision device is also smaller than that of the naked eye, which will lead to a lack of awareness of the objects in front of you (under your feet), which were originally in the weapon operation area. The peripheral vision can be seen when completing the weapon operation action to take into account, wearing a night vision camera is equivalent to a blind operation.
Proprioception refers to the sensations produced by tendons, joints, and other motor organs in different states (movement or rest), that is, the perception that people can perceive the position of various parts of the body when their eyes are closed, also known as deep sense. When the human body receives external information, more than 80% rely on vision. After wearing the night vision camera, due to the discomfort of image adaptation and field of view, the visual information will be sharply reduced, resulting in the loss of proprioception, the inability to locate the relationship between the limbs and itself and the surrounding environment and the sense of balance will deteriorate.
The above is about the physical and psychological effects of wearing a night vision camera. If you are interested in a night vision camera, you can contact us. Our website is http://www.argustecn.com/. I look forward to your arrival very much and hope to cooperate with you.
