Embodiment 1

[0033] Provided in this embodiment is a horizontal double-shutter single-layer reciprocating curtain, such as figure 1 As shown in , the moving direction of the single-layer reciprocating curtain is the horizontal direction, which includes a single-layer curtain, and two shutter slits are set at different positions in the moving direction of the curtain. Correspondingly, the single-layer reciprocating curtain is applied The two detectors of the single-layer reciprocating focal plane multi-shutter device of the type curtain also need to be arranged along the moving direction of the curtain and correspond to the positions of the slits.

Embodiment 2

[0035] Provided in this embodiment is a vertical double-shutter single-layer reciprocating curtain, such as figure 2 As shown in , the moving direction of the single-layer reciprocating curtain is the horizontal direction, which includes a single-layer curtain, and two shutter slits are arranged at different positions in the direction perpendicular to the moving direction of the curtain. Correspondingly, the application The two detectors of the single-layer reciprocating focal plane multi-shutter device of the single-layer reciprocating curtain also need to be arranged along a direction perpendicular to the moving direction of the curtain and correspond to the positions of the slits.

Embodiment 1

[0036] The difference between the implementation example 1 and the implementation example 2 is mainly caused by the different positions of the detectors in the camera structure, and there is no essential difference. These two types of single-layer reciprocating curtains are mostly used for the field of view stitching of dual-lens cameras to achieve horizontal and vertical field of view expansion respectively.

Abstract

The invention relates to the technical fields of cameras, aerial photography, remote sensing and the like, in particular to a one-layer reciprocating type curtain and a one-layer reciprocating type focal plane multi-shutter device with the one-layer reciprocating type curtain. The one-layer reciprocating type curtain comprises a one-layer curtain body. A plurality of narrow gaps are formed in the one-layer curtain body. The one-layer reciprocating type focal plane multi-shutter device comprises a plurality of detectors and the one-layer reciprocating type curtain, wherein each narrow gap corresponds to one detector. According to the one-layer reciprocating type focal plane multi-shutter device, through the one-layer reciprocating type curtain with the narrow gaps, synchronous exposure of the detectors can be conducted through the shutter narrow gaps, and high synchronization precision is guaranteed. Meanwhile, the one-layer reciprocating type focal plane multi-shutter device has the advantages of being simple in structure, easy to obtain and the like.

Description

technical field [0001] The invention relates to technical fields such as cameras, aerial photography, and remote sensing, and in particular to a single-layer reciprocating curtain and a single-layer reciprocating focal plane multi-shutter device using the single-layer reciprocating curtain. Background technique [0002] A shutter is a device used to control the exposure time of a photosensitive element or film. There are many types of shutters. For example, according to the position of the shutter, the shutter is generally divided into a central shutter (ie, the lens shutter) and a focal plane shutter (ie, the curtain shutter). There are focal plane shutters that travel vertically (vertical travel) and shutters that travel horizontally (horizontal travel). In general, the vertical-travel focal plane shutter adopts a steel sheet structure, while the horizontal-travel focal plane shutter adopts a curtain structure. [0003] In digital SLR cameras, electronically controlled v...
