The phase difference signal sent from a phase-difference detecting means 10 is inputted. A sine- variation curve of retardation due to the birefringence of the sample 6 is computed. The amplitude of the sine variation curve is obtained. The rotated angle of the 1/2-wavelength plate is obtained from the time when the rotary angle of the 1/2-wavelength plate is 0 to the time when the sine-variation curve of the retardation indicates the maximum value at first. The amount of the birefringence of the sample 6 and the main-axis orientation of the birefringence when only the residual strain is present are temporarily stored. Then, the amount of the birefringence of the sample 6 and the main-axis orientation of the birefringence are computed under the state wherein compressing stress P is applied on the sample 6, and the values are temporarily stored. The amount of the birefringence of the sample 6 and the main-axis orientation of the birefringence are computed by operating vector based on the computed values.

IPC: H01S3/097
Filed: 1984-05-30
Abstract: PURPOSE:To obtain a discharging device for improving the power source efficiency of a plurality of discharging tubes like laser tubes and minimizing the mutual interference of the discharging tubes. CONSTITUTION:Voltages are supplied from the first power source 1 to discharging tubes 31, 32,..., 3n in parallel, but voltages are supplied from the second power source via a common current control element 5 and independent resistors 61, 62,..., 6n. The irregularity of the tubes 31, 32,..., 3n are remarkable in the small current region, and the irregularity in the discharge starting voltage Es is largest. On the other hand, the irregularity in the characteristics of a maintaining discharging region is extremely small. Accordingly, when the series resistors 21, 22,..., 2n of the first power source 1 for loading the ultrafine current region are independently formed, the series current control element 5 of the second power source 4 is not particularly provided in multiple number in an independent manner. In order to compensate the ultrafine irregularity in the maintaining discharging region of discharging tubes 31, 32,..., 3n, it can be improved by inserting relatively small resistors 61, 62,..., 6n into the circuit.
