Phase modulation depth for a real-time kinoform using a liquid crystal television

Pendulum iterative algorithm for phase retrieval from modulus data

“…( 10), ( 1 2), (13), and Parseval' s theorem [that is, N2 G(u)2=' g(y)2], we obtain ( 10), ( 1 2), (13), and Parseval' s theorem [that is, N2 G(u)2=' g(y)2], we obtain…”

“…Assuming that g(x) and 0(x) are independent, we can obtain where (13) and to obtain a stable and smooth convergence, a reasonable approximation of Eqs. Assuming that g(x) and 0(x) are independent, we can obtain where (13) and to obtain a stable and smooth convergence, a reasonable approximation of Eqs.…”

<title>Applications of liquid crystal spatial light modulators to optical information processing systems</title>

“…All LCTVs are color. It is difficult to employ the LC display of a color pocket LCTV, because: (1) it is difficult to remove the color filter, and (2) since there are three color pixels to visually form an image element, although the filter is removed, when a color video signal drives the display (since optical signal processing is monochromatic), only one of three pixels is activated and two pixels are left unused as deadzone. Before the LC-SLM module is available, about five years ago, we purchased a projection LCTV, for about $3,000, containing three independent and identical LC displays.…”

Diffraction efficiency of phase-only diffractive elements displayed onto twisted nematic liquid crystal displays

“…However, when used for applications in diffractive optics, amplitude-only modulation, or phase-only modulation are most desirable. Early works on this subject demonstrated phase only-modulation by using the LCD inserted between two linear polarizers [6,7]. However, newer LCDs are thiner and they can not produce a phase-only modulation arriving to 2rc phase with linear polarizers.…”
