Example Embodiment

[0016] Such as figure 1 with figure 2 As shown, the present invention includes a focusing structure 1, an achromatic doublet lens 2, a lens barrel 3, an elastic hood 4, a protective glass 5, a first reflector 6, a base table 7, a receiving surface 8, a laser pointer 9, The second reflection mirror 10. The invention includes two working modes: optical path adjustment mode and imaging test mode. The focusing mechanism 1 and the laser pointer 9 can be installed or removed from the test system respectively. In the optical path adjustment mode, the laser pointer 9 is used to adjust the optical path; in the imaging test mode, the focusing mechanism 1 is used to perform work.

[0017] (1) Install an elastic hood 4 at the interface between the imaging test system and the aerial camera. When adjusting the light path mode, lower the elastic hood 4 to facilitate the installation of a second mirror 6 at the aircraft window to adjust the light path; In the test mode, raise the hood to suppres...

Abstract

The invention discloses a field imaging test system for an aerial camera, which is characterized by comprising a focusing structure, an achromatic doublet lens, a lens barrel, an elastic hood, protective glass, a first reflector, a base platform, a receiving surface, a laser pen and a second reflector, and having two working modes, namely a light path adjusting mode and an imaging test mode. The test system can perform field imaging test and focusing on the aerial camera in an external field more conveniently, quickly and effectively before an airplane takes off.

Description

technical field [0001] The invention belongs to the field of optical-mechanical design, in particular to an aerial camera on-site imaging test system. Background technique [0002] Some aerial cameras need to perform imaging tests and focus adjustments before the plane takes off. However, because aerial cameras often image distant objects (often thousands or even tens of thousands of meters), the camera window is facing the ground. , the object distance is very short; at the same time, it is often difficult to detect it due to the limitation of the airport area. The traditional method of using light pipe detection often requires extremely professional personnel to operate, which is labor-intensive and time-consuming. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art and provide an on-site imaging test system for aerial cameras, which can more conveniently and quickly perform on-site imaging tests and fo...
