SIMULATION METHOD FOR DESIGNING IN-AIRCRAFT OPTICAL COMPONENT

PROBLEM TO BE SOLVED: To perform prior evaluation of visibility without making a prototype and easily, when designing an optical filter which protects the eyes of a pilot from laser light in a cockpit. SOLUTION: The wavelength distribution of light, passed through a filter, is calculated from the transmission wavelength characteristics of the designed filter and wavelength distribution characteristics of light incident on the filter from an object to be visually identified under the supposition of being in a cockpit environment (S7). The wavelength distribution is converted into tristimulus values in XYZ color specification system (S8) and is converted into values, indicating the RGB three primary colors distribution displayable on a display device (S9). Using these values, a virtual image of the object to be visually identified viewed from the pilot is reconstructed on a screen of a display section (S10). The visibility is thereby evaluated, and if a proper evaluation result is obtained (S11), a move to the next step of making the prototype of a specimen (S12) may be made. COPYRIGHT: (C)2005,JPO&NCIPI
