The wider area viewing, consistent scales through the entire frame for accurate measurement are just two … The oblique photography, technology can realize a non-contact, highly automated, and high-precision measurement method. No shift in the center of lift (if the sweep angle is higher than the Mach angle). Most of time vertical photography use single lens camera to acquire remotely sensed image. A light aircraft can be easily manoeuvred and a number of views taken from different angles. The relation of oblique beam passage and change in path length has been derived in section IV-B. In case of a breakdown of the electrical turret traverse the gunner could operate a lever to switch over to traverse the turret manually.
