Abstract

We redesigned the RGB colour separation prism to decrease its size without reducing the light passing through and still obtain the efficient colour separation. The ideal dimensions of the prism based on the principles of the maximum ratios of aperture to length and aperture to height were calculated. The two aperture values were similar, but the field-of-view angle is 30.74° when the ratio of aperture to length is maximum which is 11.64° greater than the other principle. Therefore, we focused the design on the former. TFCalc software was used to design and optimize the colour separation films and we got the films with great performance of colour separation and depolarization. Finally, simulations in ZEMAX software showed that the prism aperture value reached 99.5% of the theoretical. Our strategy validates the consideration of the ratio of the aperture to length to get smaller efficient RGB colour separation prisms.

基于最大孔径长度比的RGB分色棱镜的设计

我们重新设计了RGB分色棱镜，在不减少通过光的情况下减小其尺寸，仍然可以获得有效的分色效果。根据最大孔径长比和最大孔径高比的原理，计算出了棱镜的理想尺寸。两种原理孔径值相似，但孔径长比最大时视场角为30.74°，比另一种原理大11.64°。因此，我们的设计重点是前者。利用TFCalc软件对分色膜进行了设计和优化，得到了分色退偏性能良好的分色膜。最后在ZEMAX软件中进行仿真，结果表明棱镜孔径值达到理论值的99.5%。我们的策略验证了考虑孔径与长度的比例，以获得更小的高效RGB分色棱镜。

期刊介绍： The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope. Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. General topics covered include: • Optical and photonic materials (inc. metamaterials) • Plasmonics and nanophotonics • Quantum optics (inc. quantum information) • Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers) • Coherence, propagation, polarization and manipulation (classical optics) • Scattering and holography (diffractive optics) • Optical fibres and optical communications (inc. integrated optics, amplifiers) • Vision science and applications • Medical and biomedical optics • Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy) • Imaging and Image processing
