The report describes the design of a broadband laser beam digital deflector feasibility model. This model will be a flexible broadband assembly permitting evaluation of numerous broadbanding techniques. Two methods of externally modifying an existing single wavelength digital deflector are described. Both methods provide a beam deflection system operating throughout the 4500A to 7000A portion of the spectrum. Estimates of light intensity losses are calculated for both methods of external modification. Losses are calculated at the discrete laser wavelength to be used in the Laboratory feasibility model. The theory illustrating the method of compensation required for broadband deflector operation is explained. Sample calculations are included for compensation of a two-color model. Laboratory techniques to facilitate compensation of three- and four-color models are included. Problem areas requiring special investigation are outlined. A literary investigation of index of refraction matching fluids is included as an Appendix. The problems encountered with previously used fluids in the deflector and their possible solutions are discussed. Conclusions and recommendations concerning investigation of problem areas and laboratory fabrication of the feasibility model are given. Author
