Problems solved by technology

CN10129108A ​​shows an optical adjustment mount capable of four-dimensional adjustment, but it can only realize rotation in one direction and translation in three directions
CN103913808A provides a four-dimensional optical adjustment device, which is composed of three nested rings, and its function only realizes four-dimensional adjustment
[0005] Therefore, the existing focal plane adjustment devices all aim to increase the adjustment dimension and simplify the adjustment device, but none of them can achieve six-dimensional adjustment, and there are still problems such as large and heavy devices.

Embodiment Construction

[0053] Such as figure 1As shown, a focal plane assembly adjustment device of the present invention includes a detector 10, a detector mounting plate 20, fixing screws 71-74, locking screws 61-63, and the first set of screws 31-63 for adjusting and tightening. 34. The second set of screws 41-44, and the third set of screws 51-53.

[0054] Cooperate see figure 1 , Figure 2a , Figure 2b , Figure 3a , Figure 3b As shown, the detector 10 is fixed on the detector mounting plate 20; the fixing screws 71-74 are used to initially fix the detector mounting plate 20 on the base 100; the screws 31-34, 41-44, 51-53 are divided into three parts. The group is used for six-dimensional adjustment; the locking screws 61-63 are used to fix and lock the detector mounting plate 20.

[0055] The detector mounting plate 20 has four fixing screw holes for setting corresponding fixing screws 71-74. The mounting blocks for the four fixing screw holes are located at the four corners of the de...

Abstract

The invention relates to a focal plane assembly adjusting device and method. The focal plane assembly is composed of a detector and a detector mounting plate, and an adjusting device comprises a fixing screw, a screw for adjusting and tightening and a locking screw. Four mounting corners of the detector mounting plate are designed into flexible structures, the flexible design ensures that the detector is provided with six-dimensional degree of freedom and has necessary strength, and the adjustment of different dimensions of the detector mounting plate can be realized through the adjusting andtightening screws at different positions, so that an optical system is ensured to meet a certain precision requirement, and the detector mounting plate is locked through the locking screws after the adjustment is completed. The device is simple in structure and convenient to adjust, high-precision adjustment of the focal plane can be achieved, and six-dimensional adjustment of the focal plane assembly is achieved.

Description

technical field [0001] The invention relates to a focal plane assembly adjusting device and method, which are used for adjusting the focal plane in the field of photoelectric instruments. Background technique [0002] Detectors are used in the fields of photoelectric imaging and photoelectric sensing, so they all face the problem of detector installation. From SLR or digital cameras, astronomical telescopes, microscopes, lithography machines, to aerospace reconnaissance cameras, to photoelectric tracking and guidance, etc., whether it is for civil, scientific, or military defense, detectors are involved. adjustment. A focal plane component with excellent performance is the basic guarantee for whether the performance of the whole system is up to standard. [0003] In the prior art, the detector is fixed on the mounting plate in the focal plane assembly, and the mounting plate is connected with the base through screws. The position of the focal plane assembly is guaranteed ...
