We propose a low-cost optical system that is able to simply generate computer-generated holograms and rainbow type and truecolor Lippmann type holograms. In this system, a microimaging system is applied to reduce the digitized optical data/patterns to achieve about 0.45 μm of optical resolution for rainbow hologram recording and an about 60-deg viewing angle for the Lippmann hologram. The system is designed as a turn-key machine switching between different operating modes. Custom-generated software is applied to calculate and write digital fringe patterns at real-time speed. Applications for the digital rainbow hologram include computer-generated holograms, anticounterfeiting security labels, 3-D display, and 2-D/3-D truecolor holographic stereogram images for the Lippmann hologram. This single-process synthesizing system can be considered as a fully functioning hologram printer. C 2010 Society of Photo-Optical Instrumentation Engineers.

“…Then, these technologies have been widely applied to several formats of multiplex holography, including the planar, cylindrical, conical, and disk types. [13][14][15][16][17][18] Cross 19) devised a cylindrical-type multiplex hologram and Japanese scientists invented a conical holographic stereogram. 20,21) The disktype multiplex hologram (DTMH) was invented in 1999 owing to the potential utilization of the well-developed compact disc (CD) technology and was then modified to the image-plane disk-type multiplex hologram (IPDTMH) to solve the problem of the "picket-fence effect" occurring in conventional multiplex holography.…”

The fabrication methods and parameter design for both real-image generation and virtual-image display in image-plane disk-type multiplex holography are introduced in this paper. A theoretical model of a disk-type hologram is also presented and is then used in our two-step holographic processes, including the production of a non-image-plane master hologram and optical replication using a single-beam copying system for the production of duplicated holograms. Experimental results are also presented to verify the possibility of mass production using the one-shot holographic display technology described in this study.

“…Owing to the unique 1-D focusing and beam shaping capabilities, they are widely utilized in a variety of applications such as laser diode collimation, barcode scanning, slit detector array illumination, optical microscopy, holography, microlens arrays, and digital projection display and finger print scanning [1][2][3][4][5][6][7][8][9][10]. Conventional cylindrical lenses are predominantly refraction-based and hence inherently subject to two major disadvantages: chromatic aberration and lower transmission due to dispersion and absorption of light by the lens materials, respectively.…”

Abstract:We present a wide-angle, broad-spectrum cylindrical lens based on reflections from an array of three-dimensional, high-aspect-ratio micro-mirrors fabricated on a cylindrical elastomeric substrate, functionally inspired by natural reflecting superposition compound eyes. Our device can perform one-dimensional focusing and beam-shaping comparable to conventional refraction-based cylindrical lenses, while avoiding chromatic aberration. The focal length of our cylindrical lens is 1.035 mm, suitable for micro-optical systems. Moreover, it demonstrates a wide field of view of 152° without distortion, as well as modest spherical aberrations. Our work could be applied to diverse applications including laser diode collimation, barcode scanning, holography, digital projection display, microlens arrays, and optical microscopy.
