چکیده

The confocal detection principle is extended to a highly parallel optical system that continuously analyzes thousands of concurrent sample locations. This is achieved through the use of a holographic laser illumination multiplexer combined with a confocal pinhole array before a prism dispersive element used to provide spectroscopic information from each confocal volume. The system is demonstrated to detect and identify single fluorescent molecules from each of several thousand independent confocal volumes in real time.

Real-Time Detection of Single Molecules in Solution by Confocal Fluorescence Microscopy

We report real-time detection of single fluorescent molecules in solution with a simple technique that combines confocal microscopy, Waction-limited laser excitation, and a high-efficiency photon detector. The probe volume, -5.0 x 10-l6 L, is defined latitudinally by optical W a c tion and longitudinally by spherical aberration. With an unlimited excitation throughput and a low background level...

Parallel single molecule detection with a fully integrated single-photon 2x2 CMOS detector array.

We present parallel single molecule detection (SMD) and fluorescence correlation spectroscopy (FCS) experiments with a fully integrated complementary metal oxide semiconductor (CMOS) single-photon 2x2 detector array. Multifocal excitation is achieved with a diffractive optical element (DOE). Special emphasis is placed on parallelization of the total system. The performance of the novel single-p...

A Parallel Genetic Algorithm Based Method for Feature Subset Selection in Intrusion Detection Systems

Intrusion detection systems are designed to provide security in computer networks, so that if the attacker crosses other security devices, they can detect and prevent the attack process. One of the most essential challenges in designing these systems is the so called curse of dimensionality. Therefore, in order to obtain satisfactory performance in these systems we have to take advantage of app...
