<p>In a readout apparatus for a ring laser gyroscope the optically combined readout beams (DBS1, DBS2) are reduced in size by concave mirors (245, 240) whose focal point (SP1, SP2) is located near the photoelectric detector (260, 265). The light paths (P1, P2) from the concave mirrors to the detectors pass through the same optical means (20, 30) which guides the readout beams (101A, 102A) to the beam combining means (36) and to the mirrors.</p> |
