Embodiment Construction

[0030] Combine below Figure 1 to Figure 6-2 A preferred embodiment of the present invention is given mainly to further describe the features of the present invention in detail, rather than to limit the scope of the present invention.

[0031] see first figure 1 , figure 1 It is a simplified model diagram of a multi-purpose infinity target simulation device of a specific embodiment of the present invention. The multi-purpose infinity target simulation device includes a large-diameter long focal length collimator 1 and a focal plane assembly 2. The focal length of the collimator 1 is 4 meters , the aperture is 500 mm, the focal plane assembly 2 is placed at the focal plane position of the collimator 1, therefore, the light from the focal plane assembly 2 becomes parallel light after passing through the collimator 1 and exits from the collimator 1 , so as to achieve the purpose of simulating an infinite target.

[0032] see again figure 2 and image 3 , they are all schema...

Abstract

Disclosed is a multi-function infinite distance target simulation apparatus which comprises parallel light tubes and focal surface, wherein the focal surface comprises standard object screen series, object screen mount, light source component, motor driving device and control box; and the standard object screen series comprise a group of object screens of pattern central position but different patterns and pattern sizes, same screen overall size and same connecting tape with mounts; the screens being placed on the parallel light tubes focal surface and linearly moving on the focal surface along horizon to simulate static / dynamic infinite distance objects of different shapes and instantaneous view fields. The inventive apparatus has the advantages of no need to install and adjust parallel light tubes focal surface frequently.

Description

Technical field: [0001] The invention relates to an infinite target simulation device, in particular to an infinite target simulation device which is used for calibration and detection of photoelectric instruments in a laboratory, and whose motion and static state are controllable. Background technique: [0002] The collimator is an important equipment for optical experiments and measurement inspections. It is a high-precision testing instrument and one of the indispensable testing instruments in factories and laboratories in my country. The collimator provides an infinite distance target for the photoelectric system, or provides a beam of parallel light. Its basic structure is to place a reticle, a star hole and other focal plane optical elements on the focal plane of a collimator objective lens. To meet the different practical requirements of the operating optical system. [0003] The collimator, especially the collimator with large aperture and long focal length, is an i...
