The second lens group 12 has the function of sensing images and converting them into digital signals, and is fixed on the fixing seat 101 of the main body 11 and extends outwards with a second optical axis X2.

The third mirror group 13 has the function of receiving laser light, and is connected to the body 10 and extends outwards with a third optical axis X3. The laser light emitted by the first mirror group 11 is reflected by the target The third mirror group 13 receives and calculates the distance between the target and the observation place.

Since the above-mentioned first, second, and third mirror groups 11, 12, and 13 respectively have the functions of observing the target, sensing the image of the target and converting it into a digital signal, and receiving the laser light signal reflected by the target function, so during manufacturing, the first, second, and third optical axes X1, X2, and X3 must be parallel and consistent, so that the incident light angles of the three corresponding to the target are consistent and the same, without There are errors. Therefore, in order to achieve the most accurate observation, distance measurement, and use of sensing images, each optical observation device must first be adjusted to adjust the optical axis to be parallel and consistent before leaving the factory.

However, in the actual manufacturing and optical axis adjustment operations, there are many disadvantages due to the limitation of the above-mentioned structure, among which the second lens group 12 is the most likely to cause problems, such as:

1. There are many uncertain factors in the process of processing and assembly, such as the manufacturing error of the fixing base 101 and the second mirror group 12, and the displacement error generated during the assembly and screw locking between the two, etc., which will cause the above optical axis The disadvantage of not being able to align in parallel occurs.

2. Since the fixing base 101 and the main body 10, the fixing base 101 and the second mirror group 12 are in a fixed state, it is difficult to adjust the optical axis, and after the installation of the second mirror group 12 is completed, if it is found that The optical axis is deviated, and it is quite inconvenient to disassemble and adjust again.
