Matched Filtering Using Thermoplastic Optical Recording Device

Double-rotated Matched Filtering

Using the concept of steerable filters, it is possible to represent the rotation of a known template – and thus arbitrary orientations of lines or edges – as a linear combination of a fixed number of base filters, thus allowing a computationally efficient detection of 1D structures. In spite of their usefulness in many image processing areas, such structures exhibit one important drawback: Due ...

Recording Characteristics of High-Density Thin Optical Disk Using Near-Field Optical Recording

Several integrated broadcast-broadband services, such as Hybridcast, have recently been launched which allow viewers to receive content via the airwaves together with additional information about the content via the Internet. By sharing personal preferences such as viewing histories with service providers, viewers can expect more attractive and personalized services. Viewing histories used for ...

Radar Matched Filtering using the Fractional Fourier Transform

A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be correlated with the received signal which can be carried out by multiplication in the frequency domain by applying Fourier Transform (FT). Fracti...

Optical Characterization of Doped Thermoplastic and Thermosetting Polymer-Optical-Fibers

The emission properties of a graded-index thermoplastic polymer optical fiber and a step-index thermosetting one, both doped with rhodamine 6G, have been studied. The work includes a detailed analysis of the amplified spontaneous emission together with a study of the optical gains and losses of the fibers. The photostability of the emission of both types of fibers has also been investigated. Co...
