I.e. to achieve simultaneous observation of the object by two persons.
After a user presses a key in an intelligent observation mode, the main control module controls the infrared sensor to start working, when the infrared sensor detects that human eyes are close to an ocular, a level signal is fed back to the main control module, at the moment, the main control module controls the image processing module to stop working (the image processing module can be controlled by a power supply or an interrupt instruction is sent to the DSP module), and meanwhile, the display screen 6 is controlled to be extinguished (the display screen 6 can be controlled by the power supply or a driving signal), so that the display screen 6 does not display video pictures any more, and the effect of saving electricity is achieved; when the infrared sensor detects that the human eyes are far away, another level signal is fed back to the main control module, the main control module controls the image processing module and the display screen 6 to resume working, the display screen 6 starts to display images, and a user can observe a target through the display screen 6.
After the user presses the button of 'eye observation mode', the main control module outputs a control signal to the motor driving module, and at the moment, the motor driving module controls the switch motor 10 to rotate 180 degrees, so that the positions of the reflecting mirror 14 and the spectroscope 13 are interchanged. Referring to fig. 6, at this time, the mirror 14 is located on the path of the incident light in the object lens barrel 2, at this time, the incident light is totally reflected by the mirror 14 to the reflecting prism 15, the light is reflected again by the reflecting prism 15 and then directed to the eyepiece, and the user can observe the object with eyes at the end of the eyepiece barrel 3.
After the user presses the button of the 'two-way observation mode', the controller controls the switch motor 10 to rotate 180 degrees again, so that the spectroscope 13 and the reflecting mirror 14 are reset, and at the moment, the target can be observed through the ocular and the display screen 6 at the same time.
