Abstract
Ring laser gyroscopes have increased in sensitivity by six orders of magnitude over the last several decades such that they are poised to make valuable contributions to geodesy and terrestrial tests of general relativity. To fully exploit their capabilities, residual (time varying) read out errors arising from backscatter coupling must be physically minimized or otherwise compensated. We present the results of a backscatter correction process for a 12.25 m2 gyroscope with a vast improvement in long term rotational sensitivity.
