Yu-Chih Lin Real-time dynamic full-field measurement with high spatiotemporal resolution digital holographic microscopy
Yu-Chih Lin;Xian-Ru Wu;Han-Yen Tu;Chau-Jern Cheng

We present a novel real-time measurement scheme to enhance the spatiotemporal resolution in digital holographic microscopy. The single-shot non-coplanar synthetic aperture technique was proposed to achieve real-time high spatial resolution imaging. And the coded spatial multiplexing method was used to measure the temporal complex imaging of dynamic events in specimen.

Chen-Hong Liao Analysis of a coaxial holographic data storage system with considering material response function
Chen-Hong Liao;Yeh-Wei Yu;Chi-Hsiang Yang;Shiuan-Huei Lin;Tsung-Hsun Yang;Ching-Cherng Sun

In the first time, a simulation model with considering the recording dynamics of material is built and is used to simulate evolution of the grating strength of the recorded hologram in a coaxial volume holographic memory system.

Shuming Jiao Non-destructive ciphertext authentication for ghost imaging in multi-user and multi-level environment
Shuming Jiao;Changyuan Zhou;Wenbin Zou;Xia Li

This paper proposes a non-destructive ciphertext identification scheme for ghost imaging encryption systems. Our method allows a large number of hidden images to be employed for authentication by different users at various security levels without causing any damage to the original ciphertext.

Pulse Holographic Imaging in Visible and Terahertz Frequency Ranges
Nikolay V. Petrov

In this communication I will describe the methodology of some pulsed holographic imaging approaches for visible and terahertz radiation which operate in the nanosecond-femtosecond timescales. The possibilities and limitations of these time-resolved techniques as well as the solutions to overcome the restrictions will be discussed.

Chia-Lin Cheng A binary-encoded pattern for one shot profile measurements
Chia-Lin Cheng;Sih-Yue Chen;Wei-Hung Su

A one-shot profilometry for surfaces with color or reflectivity discontinuities is presented. It uses binary-encoded pattern to illuminate the inspected object and a monochromatic camera to observe the deformed fringes at another view angle. Unwrapping can be identified without ambiguity.

Xin Ji Lai Coded structured illumination with compressive sensing for resolution enhancement in digital holographic microscopy
Xin Ji Lai;Yu Chih Lin;Han Yen Tu;Chau Jern Cheng

This work presents a coded structured illumination with compressive sensing algorithm for resolution enhancement in digital holographic microscopy by using a pair of phase-type spatial light modulators. Experimental results indicate that the spatial resolution and signal-to-noise ratio of the coded SI object is efficiently improved with a single exposure.
