Electronically Generated Patterns for Testing Optical Systems
One dimensional spatial waveforms having electrically controlled periodicity, waveshape and modulation depth are displayed on a cathode ray tube. Linear light modulation is achieved by gating a linearly scanned electron beam with constant amplitude, width and variable duty cycle pulses. Appropriate waveforms can be rapidly selected to evaluate the linearity, transient response or the steady state response of an optical system.
