Description

technical field

[0001] The invention relates to the technical field of space optical remote sensors, in particular to an optical splicing focal plane assembly applied to space optical remote sensors. Background technique

[0002] With the continuous advancement of science and technology, especially the rapid development of optical technology and electronic technology, space optical remote sensors are also developing in the direction of multi-imaging spectrum, high temporal and spatial resolution, wide coverage, real-time transmission, etc. Space optical remote sensing The wide coverage of the sensor requires the focal plane component to have more pixels. However, limited by factors such as the current process conditions and manufacturing level, the number of pixels of the single-chip detector cannot meet the requirements for the use of space optical remote sensors; therefore, Multiple detectors need to be spliced ​​together to form an equivalent large-size optical focal plan...
