The concept of a programmable multipurpose computation module for residue arithmetic is introduced. A possible design for the module is also presented. The application of the computation module in mathematical computation, coding, decoding, and scaling is demonstrated. Very high throughput rate is achieved by the use of parallel computation structures and… (More)
The approach to the design of an optical computer or processor system has typically been analog in nature in the past. Recently design concepts for a numerical optical processor have evolved in which we see digital techniques implemented with optical devices. This paper describes design concepts for a numerical optical processor which is based on the… (More)
Fourier transform post processing of radiotelescope visibility function data is reviewed with emphasis on basic data properties important to optical processing architecture.
We identify shape defects on ~300 μm high solder balls by measuring the 3D profile over +/-20 degrees down the ball surface. A broadband line scan interferometer enables measurement of ball height with 125 nm axial resolution.
We present a new technology allowing on-chip integration of a micro-resonator and its energy source for fundamental studies and commercial applications. As a proof-of-concept we demonstrate four-wave mixing and Raman lines.
