Embodiment Construction

[0023] Now in conjunction with accompanying drawing, the invention is described in detail:

[0024] According to Figure 1-2, Figure 4 ~ Figure 9-4 A preferred embodiment of the present invention is given.

[0025] like Figure 5-1 to Figure 6 As shown, the shading plate 1 is composed of a cantilever 101, a cantilever 102 and an effective shading surface 103 connecting the two cantilevers 101, 102 at the center. It is divided into a shading surface and an installation matching surface. In the process, the light-shielding surface faces the photosensitive surface 2 of the CCD to avoid the contact of the effective light-shielding surface 103 due to gravity, causing damage to the CCD photosensitive surface 2; The contact area of ​​the CCD structure 3 improves the bonding strength between the light shielding plate 1 and the CCD structure 3 .

[0026] The size of the effective shading surface 103 depends on the number of CCD effective exposure pixels required by the system, and t...

Abstract

This invention relates to a method for an array to increase the CCD working frame frequency of frame transfer, which divides a MXM elementary image sensitive zone of a MXM array into a MX(M-N) elementary dimming zone and a MXN elementary exposing zone and utilizes a visor to block the CCDMX(M-N) image elements to reduce the frame transfer time and only reads out MXN image elements serially to reduce the frame period and increase the working frame frequency.

Description

Technical field: [0001] The invention relates to a method for increasing the operating frequency of an area array CCD, in particular to a solution to high frame frequency of an area array CCD used in a space-borne hyperspectral imager. Background technique: [0002] The area array CCD is the information acquisition component in the push-broom hyperspectral imager. The flying platform completes the scanning and imaging of the space dimension, and the solid self-scanning mechanism of the area array CCD completes the scanning and reading of the spectral dimension. On a spaceborne hyperspectral imager with a speed of several kilometers per second relative to the ground, in order to obtain a sufficiently high ground resolution, the CCD needs to work at a frame rate of up to hundreds of frames per second. At present, the high frame frequency area array CCD devices provided by CCD manufacturers are shown in Figure 1-1, which are basically M×M elements. In the push-broom hyperspectr...
