This feature issue is the second Joint Applied Optics (AO) and Chinese Optics Letters (COL) Feature Issue on digital holography and three-dimensional (3D) imaging. The first installment of such a joint feature issue was in 2011. I

One of the most fascinating principles in quantum mechanics must be Heisenberg’s uncertainty principle, which can be briefly stated as follows: every physical observation cannot be precisely determined without some degree of error

This paper presents progress on the characterization of guided-wave light modulators for use in a low-cost holographic video monitor based on the MIT scanned-aperture architecture. A custom-built characterization apparatus was use

Past research has demonstrated that a phase-only hologram can be obtained by down-sampling the intensity image of the object scene prior to the generation of the hologram. In this Letter, we extend the method to the generation of

A time-division multiplexing method for computer-generated holograms (CGHs) is proposed to solve the problem of the limited space-bandwidth product. A three-dimensional (3-D) scene is divided into multiple layers at different dept

Anisotropic edge enhancement is simulated using a spiral phase plate (SPP) in optical scanning holography (OSH). We propose to use a delta function and an SPP as the pupil functions to realize anisotropic edge enhancement. The int

A novel method for a full-parallax three-dimensional (3D) holographic display by means of a lens array and a holographic functional screen is proposed. The process of acquisition, coding, restoration, and display is described in d

We present a polarization-multiplexing off-axis Mach–Zehnder configuration for dual-wavelength digital holography to achieve phase imaging in one shot. In this configuration, two orthogonal linear-polarized waves with respect to d

A polarization holographic grating, which integrates the functions of a grating and a wave plate and is called a diffractive wave plate, is recorded by two beams (left and right circularly polarized) of a 532 nm laser in an azo po

Because the bottom of the cavity has the shadow and occlusion, the angle between the projection system and imaging system is limited. So the traditional fringe projection technique based on the principle of optical triangulation i

A wavelength-swept laser is constructed using a free space external cavity configuration coupled with a fiber-based ring cavity at the 850 nm region. The external cavity filter employs a galvo-mirror scanner with a diffraction gra

We produce a maximum 1.45 W laser output at 1064 nm using a neodymium-doped silicate glass fiber that has a rectangular core with dimensions of ～6.3 μm×31.5 μm. The measured divergence angles of the output laser in two dimensions

We observe a nonlinear response of a dual-wavelength Nd:YAG laser when subjected to low-frequency periodic modulations of cavity losses. The modulation frequency is far from the relaxation oscillation frequency. The harmonic reson

During the formation of sub-wavelength ripples, the initial surface plasmon (SP)-laser interference plays an important role. In this Letter, the effects of grating structures on the distribution of the absorbed laser intensity, SP

By investigating the cross-spectral density of partially coherent multi-rotating elliptical Gaussian beams (REGBs) that propagate through a focusing optical system, we obtain the radiation force on a Rayleigh particle. The radiati

A terahertz excitation source based on a dual-lateral-mode distributed Bragg reflector (DBR) laser working in the 1.5 μm range is experimentally demonstrated. By optimizing the width of the ridge waveguide, the fundamental and the

We report on the continuous-wave (CW) and passive Q-switching performance of a miniature Yb:Y3Ga5O12 crystal laser end pumped by a 935-nm diode laser. A maximum CW output power of 12.03 W is produced with an optical-to-optical eff

Pockel’s effect and optical rectification induced by the built-in electric field in the space charge region of a silicon surface layer are demonstrated in a {001}-cut high-resistance silicon crystal. The half-wave voltage is about

A field-programmable gate array (FPGA)-based large-capacity sensing network with ultra-weak fiber Bragg gratings (FBGs) is proposed and experimentally studied. The demodulation system is constructed to interrogate 1642 serial time

The interference of optically induced electric and magnetic resonances in high-refractive-index dielectric nanoparticles provides a new approach to control and shape the scattering patterns of light in the field of nanophotonics.

A lateral photovoltaic effect (LPE) is discovered in an LaTiO3+δ film epitaxially grown on a (100) SrTiO3 substrate. Under the illumination of a continuous 808 nm laser beam that is focused on the LaTiO3+δ film through the SrTiO3

A low-threshold Raman effect in a kilowatt ytterbium-doped narrowband fiber amplifier system is reported. The Raman Stokes light at 1120 nm is achieved with the total output power of only ～400 W, indicating that the Raman threshol
