This paper reports recent progress in achieving sub-half-micron feature sizes with UV laser illumination based on a novel interferometric phase shifting (IPS) technique. In the IPS arrangement, the intensity and amount of phase shift of the shifted beam can be controlled continuously and independently using the same mask. Consequently the method can be considered as a convenient general testbed...

ELECT A new idea is presented to boost the phase shifting range of a reflective-type phase shifter (RTPS) by leveraging the parasitic capacitance; however, without any cost or design overhead. In contrast to the conventional RTPS, where the parasitic capacitance degrades the phase shifting range, a simple position interchange of electronic components leads to an enlarged tuning range. This mech...

stepped frequency radars attract many attentions due to their high range resolution. conventional processing technique in these radars is based on the idft. in detecting moving targets, the idft has the problems of range shifting and range spreading, which result in degrading target amplitude, loss of range accuracy and range resolution. to overcome these problems, the velocity compensation met...

This paper presents a multi agent system for the job shop scheduling problems. The proposed system consists of initial scheduling agent, search agents, and schedule management agent. In initial scheduling agent, a modified Shifting Bottleneck is proposed. That is, an effective heuristic approach and can generate a good solution in a low computational effort. In search agents, a hybrid search ap...

For a Sequentially Consistent implementation, there is no lower bound on either READ or WRITE. There exist implementations where the time required for either operation is 0. The only lower bound we’ve shown is that tREAD + tWRITE ≥ d, where d is the time required for a message to be transmitted between two neighboring processors. Nevertheless, in the previous lecture, we have a lower bound for ...

Experimental verification of our previously proposed linear phase imaging technique for differential interference contrast microscopy (DIC) microscopy is presented. This technique first applies phase-shifting methods to DIC to acquire linear phase gradient images in two orthogonal directions. A special Fourier integration algorithm is then applied to the combined phase gradient images to create...

Three-dimensional profilometry by sinusoidal fringe projection using phase-shifting algorithms is usually distorted by the nonlinear intensity response of commercial video projectors. To overcome this problem, several methods including sinusoidal pulse width modulation (SPWM) were proposed to generate sinusoidal fringe patterns with binary ones by defocusing the project to some certain extent. ...
