TL;DR: A computer-generated hologram is introduced onto SLM for performing the beam conversion and optical realization of a variety of polarization configurations confirms the reliability and flexibility of the method.
Abstract: We describe a convenient approach for generating arbitrary vector beams in a 4-f system with a spatial light modulator (SLM) and a common path interferometric arrangement. A computer-generated hologram is introduced onto SLM for performing the beam conversion. Optical realization of a variety of polarization configurations confirms the reliability and flexibility of our method.

TL;DR: It is shown analytically and experimentally that such a vortex can be approximately generated in the Fourier transforming optical system with a computer-controlled liquid-crystal spatial light modulator.
Abstract: We introduce the concept of the perfect optical vortex whose dark hollow radius does not depend on the topological charge. It is shown analytically and experimentally that such a vortex can be approximately generated in the Fourier transforming optical system with a computer-controlled liquid-crystal spatial light modulator.

TL;DR: The first comprehensive review of the Texas Instruments deformable-mirror device (DMD) is presented in this paper, where the DMD architecture, fabrication, and operation (both analog and digital) are described.
Abstract: A brief overview of deformable-mirror spatial light modulator (SLM) technology is presented, followed by the first comprehensive review of the Texas Instruments deformable-mirror device (DMD), a subclass of deformable-mirror SLMs. The DMD architecture, fabrication, and operation (both analog and digital) are described. It is shown that amplitude-dominant or phase-dominant modulation is obtained by a simple modification of the pixel architecture. Representative DMD applications are presented.

TL;DR: In this paper, a motionless microscopy system (FINCHSCOPE) based on Fresnel incoherent correlation holography is presented for high-resolution 3D fluorescent images of biological speciments without the need for any moving parts.
Abstract: Holography is an attractive imaging technique as it offers the ability to view a complete three-dimensional volume from one image. However, holography is not widely applied to the field of three-dimensional fluorescence microscopic imaging, because fluorescence is incoherent and creating holograms requires a coherent interferometer system. Although scanning one beam of an interferometer pattern across the rear aperture of an objective to excite fluorescence in a specimen overcomes the coherence limitation, the mechanical scanning is complicated, which makes the image capturing slow, and the process is limited to low-numerical-aperture objectives. Here we present the first demonstration of a motionless microscopy system (FINCHSCOPE) based on Fresnel incoherent correlation holography, and its use in recording high-resolution three-dimensional fluorescent images of biological specimens. By using high-numerical-aperture objectives, a spatial light modulator, a CCD camera and some simple filters, FINCHSCOPE enables the acquisition of three-dimensional microscopic images without the need for scanning. Demonstration of an imaging system that can capture high-resolution 3D fluorescent images of biological speciments without the need for any moving parts.
