Contractor Prototype Qualification Test (PQT-C) M60A1(PI) Tank Thermal Sight (TTS) AN/VSG-2.
Abstract
The M60A1(PI) Tank Thermal Sight (TTS), integrated day/night gunner's periscope, provides the commander and gunner of the M60A1(PI) tank with an improved capability for target acquisition, recognition and fire control at night. The requirement for passive operation for long range detection, recognition, and engagement precludes the use of existing image intensification devices, which require active sources of illumination for satisfactory long range operation. The system consists of five (5) major assemblies: Head Assembly, Gunner's Display, Commander's Display, Power Converter, and Mount. The TTS provides an 8X visible channel, a 1X unity window, and a dual field of view thermal channel which can be used for viewing during both the day and night time. The system is fully integrated with the tank fire control computer and laser rangefinder. The mount interfaces the Head Assembly with the tank. The Head Assembly contains the entrance window and mirror for the visible and thermal channels, as well as the afocal and the far infrared common modules that convert the IR radiation into an electronic signal and then into a visible image on the light emitting diodes. The Gunner's Display contains the 8X channel, the 8X and thermal reticle projector assembly and projection optics, the thermal channel image intensifier and biocular eyepiece. The Commander's Display contains the relay optics, and image intensifier and biocular eyepiece. The power converter contains all the electronics necessary to convert the tank power (18-30 vdc) into the voltages requires to operate the components of the head assembly, gunner's display and commander's display.
