“…19 notice that T at l = 0.6328 μm of QP covered by PITO1500 is nearly the same as it was for a clean QP substrate. The thickness d~35 μm and n~1.6 of PITO1500 layer (which are in good agreement with data from the article [31]), as well its absorption A PITO150~0 .3% and reflection R QP−PITO1500~0 .1% were estimated by mentioned above computer calculations at l = 0.6328 μm for a stock of Air | QP | PITO1500 | Air. Our investigations described in the subsection 3 indicate that absorption A LC of 13.6 μm thick layer of HBLCM at l = 0.6328 μm is smaller than 0.1%.…”

“…To eliminate the relatively high reflections (R 1 in the glass cell) on external surfaces of LCHWP, Anti−Reflecting To lower optical losses caused by absorption A ITO of con− ductive dense ITO electrodes and Fresnel reflective losses (R 2 in the glass cell) caused by optical interfaces between ITO layers and QP substrates, the QP were covered by index matched Porous ITO (PITO) layers by using vacuum deposi− tion technique [4,31]. The refractive index of PITO layer is given by the special combination of the refractive index of air (n = 1.00) and dense ITO layer (n = 2.1) [25].…”

There exists a need in a quality and accuracy of a three-dimensional laser metrology operating in numerically controlled automatic machines. For this purpose, one sends three laser beams mutually perpendicular. These three beams of the wavelength λ = 0.6328 μm are generated by the same laser and are directed along three independent, orthogonal, mutually perpendicular, optical paths with a given light polarization plain. Using these beams, constituting the frame of coordinates, three independent laser rangefinders are able to determine spatial coordinates of a working tool or a workpiece. To form these optical pulses, a special refractive index matched Half-Wave Plate with nematic Liquid Crystal (LCHWP) was applied. The presented half-wave plate is based on a single Twisted Nematic (TN) cell (with the twist angle

“…The ITO(40)/Ag(15)/ITO(40 nm) hybrid layer shows nearly the same transmittance as the 95 nm ITO monolayer. Notably, the ITO(40)/Ag(10)/ITO(40 nm) layer shows a clearly higher transmittance (86.9%) than the ITO monolayer (81.6%), as a result of index-matching of the OMO structure [19,20]. These data confirm that the hybrid layer is a key factor determining both the electrical and optical properties.…”

Transparent film heaters (TFHs) based on Joule heating are currently an active research area. However, TFHs based on an indium tin oxide (ITO) monolayer have a number of problems. For example, heating is concentrated in only part of the device. Also, heating efficiency is low because it has high sheet resistance (Rs). To address these problems, this study introduced hybrid layers of ITO/Ag/ITO deposited by magnetron sputtering, and the electrical, optical, and thermal properties were estimated for various thicknesses of the metal interlayer. The Rs of ITO(40)/Ag/ITO(40 nm) hybrid TFHs were 5.33, 3.29 and 2.15 Ω/□ for Ag thicknesses of 10, 15, and 20 nm, respectively, while the Rs of an ITO monolayer (95 nm) was 59.58 Ω/□. The maximum temperatures of these hybrid TFHs were 92, 131, and 145°C, respectively, under a voltage of 3 V. And that of the ITO monolayer was only 32°C. For the same total thickness of 95 nm, the heat generation rate (HGR) of the hybrid produced a temperature approximately 100°C higher than the ITO monolayer. It was confirmed that the film with the lowest Rs of the samples had the highest HGR for the same applied voltage. Overall, hybrid layers of ITO/Ag/ITO showed excellent performance for HGR, uniformity of heat distribution, and thermal response time.

“…In order to lower optical losses caused by absorption in conductive ITO electrodes and reflective losses caused by interfaces between ITO layers and QP substrates, the QP substrates were covered by index matched porous ITO (PITO) layers by using vacuum deposition technique [13]. Three PITO films were deposited on three QP substrates.…”

Liquid crystal cell (LCC) for space-borne laser rangefinder to space mission applications was developed, manufactured and tested under cooperation between Military University of Technology (MUT) in Poland and Vavilov State Optical Institute (Vavilov SOI) in Russia. LCC operates in twisted nematic mode, commutating the polarization plane of a laser beam working at 1.064 μm and the energy density not smaller than 0,15 J/cm2 at the pulse duration about 8 ns. The transmission of LCC is not smaller than 95% at the aperture diameter not less than 15 mm. Switching on and switching off times in a 2.5-μm thick LCC driven by voltage of 10 V are not larger than 0.7 ms and 7 ms, respectively, in the operating temperature range from 20°C to 40°C. The LCCs developed in MUT were positively tested under space requirements in Vavilov SOI.
