In the athermal design of the optical system, the collection of the temperature compensated focusing curve is the most time-consuming, laborious, and prone to deviation. In this paper, an automatic test techinique for optical athermal focusing curve is proposed, which is to collect the picture imaged of four-bar target at a certain temperature acquired by a imaging system, automatically confirm the image resolution through image algorithm, record the focal length in the clearest state, and finally automatically fit the temperature compensated focusing curve after all focal length within the operation temperature are gone through. Experiments show that this method can automatically collect and fit the temperature compensated focusing curve, which saves time, labor and enhances accuracy.

In this paper, a performance test system is designed, which is used to produce the difference in temperature between the target and the background, and simulate the infinite infrared targets. The medium-wave imaging system detects infrared target and generates target image. The evaluation of the performance of the medium-wave imaging system is completed by using the standard test method and data processing and analysis of images in the laboratory. The test system, which has the field of view of 30°×30°, the focal length of 34mm, and the distortion is less than 3%, could meet the need of testing the temperature sensitivity, resolution and transfer function of the medium-wave imaging system which the field of view is more than 90°.

The measurement and calibration of the laser diffuse reflection characteristic from target is crucial for the evaluation of laser system.A target laser diffuse reflectance test system consisting of a large-diameter laser energy analyzer is described.The structure of this system ensures that the CCD observation system and 1.57 μm laser detector have the same optical axis.The CCD observation system and laser energy meter have same mechanism.With calibration results and experiment results,it is shown that the accuracy of laser diffuse reflection from target is high,and the test method is operationally excellent.

In military and industrial sectors, automatic test system remarkably reduces maintenance cost of certain equipments. As is depicted in the thesis, the highly adaptive automatic test software architecture is presented with multiple common data interfaces, which not only enables rapid prototyping of automatic test procedure, but also collectively facilitate information sharing and data exchange in the whole lifecycle.
