Microlens arrays
‡Bell Laboratories, Lucent Technologies, 600 Mountain Avenue, Murray Hill, NJ 07974, USA E-mail: [email protected] Microlenses are important optical components that image, detect, and couple light. But most synthetic microlenses have fixed position and shape once they are fabricated, so their possible range of tunability and complexity is rather limited. By comparison, biology provides many...
متن کاملPose Hashing with Microlens Arrays
We design and demonstrate a passive physical object whose appearance changes to give a discrete encoding of its pose. This object is created with a microlens array that is placed on top of a black and white pattern. When viewed from a particular viewpoint, the lenses appear black or white depending on the part of the pattern that each microlens projects towards that viewpoint. We introduce the ...
متن کاملLarge Area Full Fill Factor Microlens Arrays
Production of microlens arrays using the resist reflow technique has been extensively reported1,2. Theses arrays have fill factors approaching 75% and in lensed systems the unlensed light introduces noise into the imaging system. N T Gordon, C L Jones and D Purdy3 reported a sophisticated techniques able to create full fill, however, this is expensive. Davies and McCormick4, using optical litho...
متن کاملHigh-resolution beam steering using microlens arrays.
Imaging or beam-steering systems employing a periodic array of microlenses or micromirrors suffer from diffraction problems resulting from the destructive interference of the beam segments produced by the array. Simple formulas are derived for beam steering with segmented apertures that do not suffer from diffraction problems because of the introduction of a moving linear phase shifter such as ...
متن کاملSequential shrink photolithography for plastic microlens arrays.
Endeavoring to push the boundaries of microfabrication with shrinkable polymers, we have developed a sequential shrink photolithography process. We demonstrate the utility of this approach by rapidly fabricating plastic microlens arrays. First, we create a mask out of the children's toy Shrinky Dinks by simply printing dots using a standard desktop printer. Upon retraction of this pre-stressed ...
