Journal ArticleDOI
A holistic approach for Off-line handwritten cursive word recognition using directional feature based on Arnold transform
TL;DR: This paper presents a holistic off-line handwriting recognition system based on extraction of directional features which depends on the stroke orientation distribution of cursive word, which is compared with the state-of-the-art methods for handwritten character recognition using C-Cube data-set.
Journal ArticleDOI
Transmission digital holographic microscopy based on a beam-splitter cube interferometer
TL;DR: The novelty of the proposed configuration is its simplicity, minimal number of optical elements, insensitivity to vibration, and its inherent capability to compensate for the phase curvature that results from the illuminating wavefront in the case of microscopic samples.
Journal ArticleDOI
Achromatic quarter-wave plate using crystalline quartz.
TL;DR: The present study deals with the design and characteristics of two different quarter-wave achromatic retarders in the 500-700 nm range, using a cascaded system of two birefringent plates, and appears that the proposed arrangement has the promise of producing good a chromatic combinations.
Journal ArticleDOI
Polarization phase shifting interferometric technique for phase calibration of a reflective phase spatial light modulator
TL;DR: In this paper, a full-field polarization phase shifting interferometric technique, based on the Twyman-Green interferometer, was proposed for the purpose of calibration of phase in spatial light modulators.
Journal ArticleDOI
Simulation of effects of phase and amplitude coatings on the lens aperture with polarization masks
TL;DR: In this article, the effects of such phase and amplitude coatings on the imaging properties of a lens can be achieved by using suitably oriented polarization masks on the lens aperture, which can be continuously varied by changing the orientation of the polarizing devices included in the system.
