“…Thus it is possible to construct a retardation plate of any size using only quite moderate hydraulic pressures. 3. THE HYDRAULIC PRESSURE FRAME Figure 1 (a) and (b) shows two views of a pressure frame suitable for a retardation plate 1 in.…”

“…By combining an adjustable retardation plate with each crystal plate of the filter, the effective retardation of the combination could be set to pass the desired wavelength band. Moreover, as Billings [3] has pointed out, in such a filter it is not necessary to maintain the exact 2, 4, 8 .... retardation ratio between the crystal elements, so long as the retardations differ from the correct value exactly by a small number of whole wavelengths. With calibrated retardation plates capable of adjustment over one complete wavelength it should then be possible to tune the complete Lyot filter over an extended wavelength range while maintaining a narrow pass-band.…”

A variable retardation plate suitable for polarizing optics in the visible and ultra-violet has been developed. It is based on the photoelastic effect induced by lateral compression of a rectangular plate of fused silica. A special pressure frame employing hydraulic pressure gives very even compression, and the stress pattern induced is uniform to within 1 per cent over most of the plate area. A pneumatic ballast system has also been developed to stabilize the pressure, which maintains the retardation constant to within ½ per cent over a period of hours. Possible applications of the retardation plate in optical instrumentation and in the accurate measurement of pressure are discussed.

“…A tuning range of more than 17 nm was achieved around 1540 nm. Polarization-interference birefringent filters based on the model proposed by Billings [4] have found a widespread use. Šolc and Lyot-Ohman configurations are the two most common filters in this category [5].…”

The construction of a three-stage tunable birefringent filter using variable phase shifters fabricated from ammonium dihydrogen phosphate is described and its performance, evaluated for white light with a divergence of 2-3 mrad, is found to compare well with the predicted behaviour. A brief description of the principles of operation is included. Theoretically, the filter scans the spectrum from 250 nm to 750 nm with a bandwidth ranging in value from 35 nm at 250 nm to 85 nm at 750 nm. Theoretically, the voltage necessary to scan the above spectrum range is f 25 kV. Experimentally, a bandwidth ranging from 41 nm at 350 nm to 80 nm at 700 nm was obtained. Losses at various wavelengths have been determined. For example, at the centre wavelength (500 nm) where the bandwidth was 47 nm a ratio of Iout/Iin= 1/15 was obtained. Causes for deviation between theoretical and experimental results are examined and suggestions made for further work.
