摘要：

We have investigated a zero-area Sagnac interferometer as abroad band gravitational-wave detector. Frequency response measurements of a laboratory-scale interferometer are in excellent agreement with theory. The measured contrast ratio, 0.996, is insensitive to induced birefringence, laser-frequency variation, arm imbalance, and dc mirror displacement. A near shot-noise-limited phase sensitivity of 3 x 10(-9) rad/root Hz was measured at the interferometer's maximum sensitivity frequency, 90.9 MHz.
