Description

The invention relates to optical. HaniChm instrumentation and can be used in. engineering, construction or geodesy to control the relative position of the surfaces and measure the angles between objects when working with mirrors or small prisms in poor light conditions.

Autocollimation telescopes are known, consisting of a lens, an autocollimation ocular and a direct tube body (1).

However, working with this auto collima- tional theodolite optic tube to ensure the position of mirrors or other reflecting surfaces of small size (on the order of 10-15 cm) at multimeter distances between mirrors (large 5 m) is rather time-consuming and requires a large voltage from the operator. The complexity of the process of detecting the autocollimation image of the telescope network in the visual field — the pipe increases as the mirror is removed from the pipe lens, which is due to the high sensitivity of the autocollimation method even to large rotations and inclinations or telescope.

The closest to the invention according to the technical nature is an autocollimation telescope mainly for theodolites, comprising a lighted mark, a lens in a frame, a focusing element and an autocollimation eye 2r.

A disadvantage of the known device is the difficulty of controlling the angular position of a distant object, which is due to the limited range of observed angular positions of the mirror objects.

The purpose of the invention is to simplify the monitoring of the position of remote mirror objects.

This goal is achieved by the fact that, in the autocrystalline telescope, it is preferable for the theodo- litas containing illuminated. the brand, the lens in the frame, the focusing element, and the autocollimation eyepiece, the brand is made in the form of a light diffusing ring and mounted on the front of the lens barrel coaxially with it, while

The inner diameter of the ring corresponds to the light diameter of the lens. Sequential implementation of sighting and autocollimation by the proposed device allows one to control the position of the reflected mirror objects in poor conditions. light exposure.

pipes, in FIG. 2 - illuminated mark, open;

The optical scheme of the autocollimation telescope contains objec- tine 1, illuminated mark 2, focusing element 3, - prism .4, condenser 5, incandescent bulb 6, eye 7. The solid line shows the beam path for the case of drawing an CE1 net ring. The course of the rays in the case of the construction of the autocollimation image is shown by a dotted line ..

The illuminated mark consists of a cylindrical body with a flange 8, which is attached to the rim of the telescope lens, a cartridge 9 for the incandescent bulb 10 mounted on the body: with the screws 11, scattered from the body; its light of the ring 12 that creates. equal surface around the rim of the lens.

The process of autocollimating anchorage of the proposed telescope, for example, to a fixed mirror, is carried out as follows.

When searching and pointing, two actions are accomplished: they guide the telescope to the center of the mirror and position the viewing axis of the tube perpendicular to the surface of the mirror. To do this, install the telescope and direct it to the mirror, aligning the crosshairs of the integrated grid

eyepiece pc1 with the center of the mirror. Refocus the telescope so that a reflected image of the light of the ring appears in the mirror. Consistent linear

50 displacements and turns of the telescope make it necessary to combine the built-in eyepiece grid with the center of the light of the ring and re-control the alignment of the center.

55 grids the ocular with the center of the mirror and with the center of the image the light of the ring. Then the telescope refocuses to infinity, and the lens

The proposed device is different from the known autocollimation.
