Off-axis camera for space with large field of view and highly integrated focal plane structure

Abstract

The invention discloses a large-view-field and high-integration-density focal plane structure of an off-axis camera for space. The heat conduction area of the focal plane structure is greatly increased compared with that of a focal plane structure of an off-axis camera for space in the prior art, the heat dissipating mode of combining heat tubes and cold radiating plates is adopted, the problem that due to large power consumption of the large-view-field and high-integration-density focal plane structure of the off-axis camera for space, the temperature of an imaging device of the focal plane structure rises too quickly in the working process is solved, and the situation that heat generated by multiple detectors cannot be all dissipated through a focal plane substrate, consequently, the performance of the detectors is reduced, and the imaging performance of the space remote sensing camera is reduced is avoided.

Description

technical field [0001] The invention relates to the technical field of space optical remote sensing, and more specifically relates to a large-field-of-view and high-integration focal plane structure of an off-axis camera for space. Background technique [0002] The focal plane structure of the off-axis camera for space is the main component of the off-axis camera for space, and is mainly used to set up detection elements such as sensors. Traditional single-sensor space off-axis cameras have limited resolution and field of view. With the continuous development of space remote sensing technology, researchers have put forward new requirements for space off-axis cameras with high resolution and wide field of view. Traditional single-sensor Off-axis cameras for space use can no longer meet the needs of researchers. Therefore, more sensors and corresponding electronic devices need to be integrated in the focal plane structure. [0003] In the prior art, the multiple sensors and ...
