Abstract
A method of constructing rotatable scanning prisms (13' and 13') for a multimode detection system (13), each including first and second subprisms (respectively 13'a, 13'b and 13'a, 13'b); the method including the steps of chosing an apex angle for one of said subprisms, determining therefrom apex angles at first and second wavelengths for each of said subprisms, and evaluating whether the differences of apex angles at said several wavelengths are acceptably small.
