Accurate 3-D Measurement System Using the Pico Projector-based Phase Shifting Techniques
The 3-D measurement system based on optical method is becoming widely applied. Among those methods, fringe projection techniques provide high resolution, whole-filed 3-D reconstruction of objects in non-contact manner. A custom-made LCD(Liquid Crystal Display) projector for inspection system using fringe projection and phase shifting is expensive and complex. In this paper, the 3-D measurement ...
متن کاملPico Lantern: A Pick-up Projector for Augmented Reality in Laparoscopic Surgery
The Pico Lantern is proposed as a new tool for guidance in laparoscopic surgery. Its miniaturized design allows it to be picked up by a laparoscopic tool during surgery and tracked directly by the endoscope. By using laser projection, different patterns and annotations can be projected onto the tissue surface. The first explored application is surface reconstruction. The absolute error for surf...
متن کاملSpeckle reduction and maintaining contrast in a LASER pico-projector using a vibrating symmetric diffuser.
We proposed a design for a LASER pico-projector with a low speckle contrast value and high contrast ratio that maintains system efficiency. The method for speckle contrast reduction utilizes two diffusers and a Voice Coil Motor (VCM) oscillator. The two different diffusers for a high contrast ratio and high system efficiency can be divided into two categories. In Category 1, the speckle contras...
متن کامل29.3: Very Bright and Efficient Top-Emitting OLED with Ultra-Thin Yb as Effective Electron Injector
Very bright and efficient top-emitting organic light-emitting diodes (TOLEDs) using an ultra-thin ytterbium (Yb) layer capped with a semitransparent Ag layer as the effective electron-injection cathode were demonstrated. TOLED with Yb/Ag cathode exhibited lower operation voltage and higher power efficiency, as compared to the one with commonly used Ca/Ag cathode. With bis(2-phenylpyridine)iridi...
متن کاملOptimal sub pixel arrangements and coding for ultra-high resolution three-dimensional OLED displays
To my wife and my daughter, to whom I promised this a few years ago. They fully supported me to conclude it during weekends and holidays. I promise I will not do anything like this again! To my parents, who would have liked to see it finished. Information display technology is a rapidly growing research and development field. Resolutions of TFT displays are increasing rapidly and the flat panel...
