Embodiment Construction
[0026] see figure 1 , the present invention provides an optical axis indication adjustment mechanism, the structure of its preferred embodiment includes a fixed plate 4 and a plurality of lasers arranged on the fixed plate 4; one of the lasers is a positive indicator laser 2, and the other lasers are based on The forward pointing laser 2 is a reverse pointing laser 3 arranged axially symmetric to the center. The positive direction indicates that the laser output direction of the laser 2 is the direction of the object plane, which is used to illuminate the target point, enhance the brightness of the image plane of the system, and facilitate the alignment of the recording medium. The laser emission direction of the reverse pointing laser 3 is the direction of the image plane. In this embodiment, there are four reverse pointing lasers, which are arranged symmetrically around the forward pointing lasers. The thin beams emitted by the four reverse pointing lasers are parallel to t...

The invention belongs to the optical experiment and engineering technology field and more particularly, to an optical axis indication adjusting mechanism and an indication adjusting method, wherein the optical axis indication adjusting mechanism comprises a fixed plate and a plurality of lasers arranged on the fixed plate, one of the lasers being a forward direction indication laser and the other lasers being reverse direction indication lasers with the forward direction indication laser as the centre and arranged in symmetry. The lasers of the forward direction indication laser transmit out in the direction of an object face while the lasers of the reverse direction indication lasers transmit out in the direction of the image face. According to the invention, through the arrangement of a forward direction indication laser and the reverse direction indication lasers, it is possible to indicate the positions of the image and the object accurately while the object face target is being illuminated and the brightness of the system is being strengthened so as to conveniently record the medium and the subsequent radial alignment and installation of the optical elements.
Description
technical field [0001] The invention belongs to the field of optical experiment and engineering technology, and in particular relates to an optical axis indication adjustment mechanism and an indication adjustment method thereof. Background technique [0002] In optical experiments, the alignment of the optical axis of the optical path and the placement of the recording medium often require fine-tuning of the light source to achieve the alignment and aiming process. In the absence of reliable positioning and adjustment links, it is often necessary to use V-shaped blocks or cementation to achieve. There is no quantitative control in the targeting process of this method, resulting in high randomness and low efficiency in the experiment. Especially when the target is small, the aiming beam or laser spot is larger than or close to the aiming target, making the aiming process difficult to control. Contents of the invention [0003] The object of the present invention is to pro...
