Slew models a constant slew, i.e. a continuously changing look angle, of an optical system. Slew has the same effect, and is governed by the same sign conventions, as a uniformly changing tilt. Slew takes four parameters, used to specify the initial look angle and its rate of change in x and y. A positive look angle corresponds to the platform side pointing towards +x or +y, and a positive slew rate corresponds to turning in that direction.

Slew has two Light inputs and two Light outputs, used to process incoming and outgoing light.
