The cast glance is a gyro-stabilised optical instrument in use by the United States Navy. It is an airborne system that is used by Air Test and Evaluation Squadron 30 (VX-30) on board the Lockheed NP-3D Orion. The system consists of a moving gyro-stabilised mirror with fixed optics, two fixed cameras and five sensors. The cameras look out of the starboard side of the aircraft. The system is photometric and enables the simultaneous recording of the electro-optical to the infrared spectrum and medium wave IR.
