Embodiment Construction
[0030] Combine below figure 1 ~Fig. 6-2 provides a preferred embodiment of the present invention, mainly as the characteristic of the present invention in further detail, rather than being used for limiting 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 al...

A multi-purpose infinity target simulation device, including two parts: collimator and focal plane assembly, wherein the focal plane assembly is mainly composed of standard object screen board series, object screen bracket, light source assembly, motor transmission structure and its control box, The standard object screen series is composed of a series of patterns and patterns with different sizes, but the center position of the pattern is the same, the shape of the object screen and the object screen bracket are connected in the same way. They are placed on the focal plane of the collimator. And it can move linearly along the horizontal direction on the focal plane to simulate a series of static / moving infinity targets with different shapes and different instantaneous fields of view. The invention does not require frequent adjustment of the focal plane position of the collimator to meet the different requirements for the simulation of infinite motion and stationary targets during the development, installation, debugging, and detection of photoelectric instruments. It also only needs to design, manufacture and replace the standard object screen plate to meet the requirements new requirements.
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...
