General test platform for optical performance of head-up display

Abstract

The invention discloses a general test platform for the optical performance of a head-up display. The test platform composed of a 2D rotary table, an optical platform, a portal frame, a displacement platform, a theodolite, a 2D displacement platform and a parallel light pipe detects the optical performance of the head-up display. the parallel light pipe is hoisting over the optical platform via the portal frame, the parallel light pipe can move up and down on the portal fame and move left and right over the displacement platform with the portal frame, it is ensured the exit pupil caliber of the parallel light pipe can cover the observation range of the head-up display, the 2D rotary table is directly fixed in the middle position of the optical platform, a long flat plate is mounted on the rotary table to hold the head-up display, and installation test can be carried out on head-up displays of different installation states via angle adjustment; and the theodolite is fixed to the frontmost end of the optical platform via the 2D displacement platform, and thus, the head-up display erected in the position of the flat plate on the 2D rotary table can be tested. The test platform has the advantages that resources can be utilized effectively, the platform is simple and easy to operate, a measuring result is accurate and visual, and the detection efficiency is improved.

Description

technical field [0001] The patent of the present invention belongs to the technical field of testing, and relates to a testing platform. Specifically, the optical performance of a head-up display is detected through a testing platform composed of a two-dimensional pitch adjustment platform, an optical platform, a gantry, a translation guide rail, a theodolite and a collimator. Background technique [0002] The head-up display is one of the important components of the integrated avionics fire control system. It is usually installed above the central dashboard of the cockpit. It is the main display of the aircraft and the main window for exchanging information between the pilot and the aircraft. It is controlled by the mission computer or other electronic components, converts the electrical signals sent by it into visual signals visible to the driver, and images them at infinity for the driver to control the flight of the aircraft and implement attack targeting . Therefore, w...
