FIG. 10. — Negligible degradation of MTF and DQE occurs for a 1° divergence angle, which is the worst case encountered using proposed piecewise-focused design. (a) MTF curves, (b) DQE curves, and (c) ratio of 1°/0° DQE values as a function of spatial frequency. The average measured and simulated DQE losses are 4% and 6%, respectively.
