Embodiment 1
[0055] The electronic internal focusing collimator of this embodiment has the function of self-collimation.
[0056] Adjust the floating objective lens 404 to the self-collimation position, if the focal length , the pixel unit size of the large-target high-resolution image sensor used is:
[0057]
[0058] Through the self-collimation calculation formula, the corresponding angular resolution of a single pixel can be calculated as:
[0059]
[0060] The software resolution after 64 subdivision is 0.03 , usually the detection accuracy of the measurement product is 5-10 times of the resolution, so the self-collimation angle measurement accuracy of the electronic internal focusing collimator of this embodiment can conservatively reach 0.3 .
Embodiment 2
[0062] The electronic internal focusing collimator of this embodiment has the function of a telescope.
[0063] Adjust the floating objective lens 404 to the infinity imaging position, since it directly observes the cross reticle of the autocollimation theodolite, it has a 2-fold relationship with the resolution and accuracy of the autocollimation, so the angle measurement accuracy in the telescope mode can reach 0.5 .
[0064] In the present invention, the photosensitive surface of the photoelectric sensor is directly placed in the optical conjugate plane, and the sensor pixels and the reticle are all made of semiconductor manufacturing technology to ensure their marking accuracy, so the accuracy analysis of Embodiment 1 and Embodiment 2 can be guaranteed. of.
Embodiment 3
[0066] In this embodiment, the electronic internal focusing collimator of the present invention is used to make a portable theodolite detection device.
[0067] Such as image 3 As shown, the portable theodolite detection device includes a heavy-duty tripod P3 located below, a central axis P2 fixed at the central axis position above the heavy-duty tripod P3, a leveling platform 201 is fixed on the top of the central axis P2, and a bottom plate 17 of the light tube combination box P1 Installed on the leveling platform 201;
[0068] The heavy-duty tripod P3 has two upper and lower sections, and the height can be adjusted by lifting the upper section; the opening angle of the heavy-duty tripod P3 ranges from 0° to 30°; the bottom of the heavy-duty tripod P3 is equipped with spikes for fixing;
[0069] Such as Figure 4 As shown, the leveling platform 201 of the central axis P2 is provided with three evenly distributed leveling knobs 202 for adjusting the levelness of the leveli...
