Description

Technical Field

[0001] The utility model mainly relates to the technical field of digital image source testing, in particular to an optical index testing device for measuring different angles of a digital image source. Background Art

[0002] The widespread adoption of airborne head-up displays (HUDs) has increased the demands placed on the optical performance of digital image sources. Optical specifications, such as brightness and contrast, are of particular concern. Different aircraft models have varying viewing angle requirements for digital image sources, leading to varying optical specifications within different viewing angles.

[0003] After assembling a digital image source, its specified optical parameters need to be tested. This measurement requires specialized equipment, which secures the digital image source to the test device. While flexible for testing at a specific viewing angle, visual inspection is required to ensure that the image source is rotated to the specified angle. This equipment is inconvenient, time-consuming, and space-consuming. For a large number of digital image sources, testing requires speed, efficiency, and accuracy, while also being simple to operate and portable. Even for field testing, handheld optical test equipment can be used for testing, eliminating the need for specialized training.

[0004] Therefore, it is necessary to design a device that can quickly fix the digital image source, quickly rotate the digital image source to a specified viewing angle, be easy to carry, and be simple to operate. At the same time, it can also be applied to specific digital image source equipment.

[0042] The angle indicator 6 is provided at the end of the damper 4 .

[0043] After the digital image source to be detected is fixed, the device can be rotated to any angle to perform the detection operation. When the device is working, the damper 4 is first connected to the supporting columns 2 at both ends, and then the damper 4 is connected to the fixing seat 3.

During the detection, the fixing seat 3 can be rotated at any angle in the vertical direction according to the needs of the detection instrument. During rotation, the angle indicator 6 will rotate with the rotation of the damper 4. The rotation angle of the device to be detected can be quickly known according to the reading of the angle indicator 6 on the angle indicator disk 5. The device has a simple structure, is easy to carry and assemble, can be used for work in the laboratory, and can also be carried out for measurement and is relatively convenient to operate.
