Abstract

The invention relates to a multi-optical axis consistency tester based on a multispectral target plate and a rotating reflector and belongs to the opto-electrical field. The invention comprises the main lens of a large caliber offaxis double reverse collimation mirror, the secondary mirror of the collimation mirror, a double-axis rotating mechanism, a plane mirror, an attenuator, a spectroscope A, a multispectral target plate, a spectroscope B, a near infrared CCD, an optical fiber coupler, an optical fiber, a multi-channel video collecting device, etc. The plane mirror is driven by the rotating mechanism; the multispectral target plate is arranged in the reflection optical path of the spectroscope A; after the transmission optical path of the spectroscope A passes through the spectroscope B, the transmission light enters the near infrared CCD; simultaneously the reflection light enters the incident end of the optical fiber; the other end of the optical fiber is connected with the transmitting end of the laser range measuring machine of the optical fiber coupler; a laser pulse is coupled with and enters the optical fiber. The multi-optical axis consistency instrument device is used for detecting the static and dynamic errors of the consistency between the multi-optical axes in the broad spectrum range of a complex opto-electrical system, has high precision and is conveniently carried.

Description

technical field [0001] The invention relates to a portable test device for testing the consistency of multiple optical axes in a complex optoelectronic system in a wide spectral range. The device can be used to measure the consistency of optical axes of a complex optoelectronic system with multiple optical sub-systems arranged in parallel, and belongs to the field of optoelectronics . Background technique [0002] In recent years, with the wide application of various photoelectric instruments in large-scale photoelectric sights and tracking systems, photoelectric systems include not only visible light sighting equipment, laser ranging equipment, but also infrared sighting, TV tracking and sighting tests, etc. The range covers almost all bands from visible light to infrared light, and the total number of optical axes is as many as five or more, including infrared sighting axis, TV tracking axis, laser ranging aiming axis, transmitting axis, receiving axis, etc. In order to i...
