Researches on Performance Improvement of Integral Imaging Display Technology

Integral imaging is a true 3D display technology which uses the micro-lens array to record and reconstruct the 3D scene.Researches are carried out to solve some problems of the integral imaging including black zone,narrow viewing angle,inefficiency and inaccurate depth calculation.This paper proposes a digital secondary pickup process without black zone,an integral imaging display with wide viewing angle and a rapid computer generated integral imaging.Also,we analyze the integral imaging depth range and deduce the depth calculation formulas in different display modes by using the distribution model of the Gaussian beam.These researches help to improve the performances of the integral imaging system.
