System analysis is the technique of determining the utility of the overall photoelectronic system to the end user. The procedure commences with a search for the user’s total problem and terminates, as a goal, with its optimum solution. The first step to be undertaken in system engineering is the determination of all boundaries and constraints that surround the total problem. As an example, the system boundaries might include the television scenery, lighting, makeup, air conditioning, cost, reliability, and maintenance, as well as all other photoelectronic technical considerations that go into making a television-broadcast complex. Or, in contrast, the system boundary may be limited by an objective lens of a telescope for astronomical observations, and terminate with an electronically enhanced display device for one observer at the other end of the system. Since each application of photoelectronics is different, the analytical approach for system analysis is also different. Factors that are of major concern to one user may be wholly unimportant for other applications, and impact the methodology required for system analysis accordingly.
