A productized liquid crystal reticle LCR was designed, fabricated and tested with 49 lines for elevation and 299 lines for azimuth. The prototype LCR incorporated a shock and vibration resistant mounting scheme with transparent thin film heater. This LCR was installed on a thermal nightsight using essentially the same volume as the existing fixed reticle. The LCR was operated on the thermal nightsight using a separate simple electronics controller with only one reticle line not functional. Results from this task demonstrated that a LCR, designed to withstand the armored vehicle environment, can be installed and operated with a thermal nightsight. Author
