Conoscopic holography, which consists of two circular polarizers and an uniaxial crystal, is incoherent holographic technology for three-dimensional display and non-contact diagnosis. In this paper, we derive the longitudinal and lateral intensities from point-source hologram made by conoscopic holography. Also, the longitudinal and lateral resolutions of conoscopic holography will be obtained from the longitudinal and lateral intensities, respectively, according to Rayleigh criterion.

Conoscopic holography, which consists of two linear polarizers and two wave plates, and an uniaxial crystal, is incoherent holographic technology for three-dimensional display. In the uniaxial crystal, the wave from object divides into extraordinary and ordinary waves and phase difference between two waves is caused by the different refractive index of two waves. Four intensity patterns, which are made by phase difference, are obtained using LCLV(liquid crystal light valve) and conoscopic holography system. By combining four intensity patterns, the complex hologram without bias and conjugate image. In this paper, we propose the optimized system, which consists of a wave plate and a linear polarizer, and uniaxial crystal. In the proposed system, it doesn't need LCLV. By adjusting the azimuth angle of a linear polarizer and a wave plate, we derive four intensity patterns in recording plane. We demonstrate theoretically that the complex hologram with bias and a conjugate image is obtained using the proposed system.
