The present invention is directed to missile training systems, especially to those relating to the provision of a mechanism that allows missiles and similar devices to be fired at a target in a realistic, but safe, manner. The image warping software algorithm alters the display scene and allows an observer to view the display scene as a single unbroken image when the display scene is distributed across multiple display screens. 0 m by undergoing a drawing step after the ironing step. In order to enable a calibration of the sensor with a higher precision compared to a known calibration fluid of this type both in vivo as well as in vitro, the ionic strength of the fluid at 37 C. A common modulated current is injected into each optical amplification region through the p-electrode.
