Simultaneous multicolor image formation with a single diffractive optical element.

چکیده
A design for a novel diffractive optical element (DOE) that can reconstruct three different intensity patterns when it is illuminated by three different wavelengths is presented. If the chosen wavelengths are red, green, and blue, full-color reconstruction capability is obtained. Reconstruction is achieved in the near field (Fresnel domain). Computer simulation results as well as experimental evidence are presented, proving the capabilities of this novel DOE design procedure.

Five beam holographic lithography for simultaneous fabrication of three dimensional photonic crystal templates and line defects using phase tunable diffractive optical element.
This paper demonstrates an approach for laser holographic patterning of three-dimensional photonic lattice structures using a single diffractive optical element. The diffractive optical element is fabricated by recording gratings in a photosensitive polymer using a two-beam interference method and has four diffraction gratings oriented with four-fold symmetry around a central opening. Four firs...
متن کاملEfficiency analysis of diffractive lenses.
Multilevel diffractive optical elements are necessary for achieving high-efficiency performance. Here the diffraction efficiency of a multilevel phase-only diffractive lens is analyzed. Approximate, as well as more accurate, approaches are presented. Both plane-wave and Gaussian illumination are discussed. It is shown that for many practical cases the diffraction efficiency can be determined by...
متن کاملFluorescence incoherent color holography.
We present a new imaging method to record multicolor digital holograms from objects emitting fluorescent light. The fluorescent light specific to the emission wavelength of various fluorescent dyes after excitation of three dimensional (3D) objects is recorded on a digital monochrome camera after reflection from a diffractive optical element (DOE). For each wavelength of fluorescent emission, t...

60 | VOL.10 NO.1 | JANUARY 2013 | nature methods fluorescence microscopy using beam splitters to image up to four focal planes on separate cameras3. This method provides excellent light efficiency and a large lateral field of view corresponding to the entire surface area of the camera chip. However, refocusing by translating the camera away from the nominal focal plane induces spherical aberrat...
متن کاملSingle-frame measurement of the complete spatiotemporal intensity and phase of ultrashort laser pulses using wavelength-multiplexed digital holography
We show that a simple (few-element) arrangement for wavelength-multiplexed digital holography allows the measurement of the electric field E x ,y , t of a femtosecond laser pulse on a single shot. A slightly rotated twodimensional diffractive optical element and a variable-wavelength filter together generate multiple spectrally resolved digital holograms that are simultaneously captured in a si...
