An optical data storage system is contemplated, one employing a data-modulated writing laser beam (FIG. 2: .circle.L ) with improved associated optical media (FIG. 2), these characterized by multiple layers (FIG. 2:c,d,e,f,g)--more particularly, a highly reflective aluminum layer (c), a relatively transparent polymer spacer layer (d) overlying the reflective layer, and an optical absorber (recording) layer (e) overlying the spacer layer, plus an overcoating structure, e.g., as a "soft pad" layer (f; e.g., a fluoropolymer) on the absorber, with a "Hard" layer (g; e.g., a radiation-cured acrylic) laid over the "soft pad" as an outer protective overcoat. "Spiral" coating techniques (FIG. 3) are specified for applying the "Hard" layer.

The present disclosure relates to a frequency synthesizer. The frequency synthesizer includes a phase comparator having first and second input nodes. The first input node receives a reference signal having a reference frequency. A channel control block has an input that receives a channel word and an output coupled to the second input node of the phase comparator. A local oscillator (LO) output node provides an LO signal having an LO frequency based on the reference frequency and the channel word. A feedback back couples the LO output node to the second input node of the phase comparator through the channel control block. A non-linear error correction element is operably coupled on a coupling path extending between the phase comparator and the DCO.

Embodiments of the present invention create a circuit having a digital-to-time converter with a high-frequency input for receiving a high-frequency signal, a digital input for receiving a first digital signal, and a high-frequency output for the provision of a chronologically delayed version of the HF signal. In addition, the circuit has an oscillator arrangement for the provision of the high-frequency signal, having a phase-locked loop for adjusting a frequency of the high-frequency signal. The digital-to-time converter is designed to chronologically delay the received high-frequency signal based on the first digital signal received at its digital input.

One embodiment of the present invention relates to a modulation system having a phase locked loop and an adaptive control. The phased lock loop is configured to receive an input signal and an adaptive signal. The input signal is an unmodulated signal, such as a phase component or phase signal. The phase locked loop is also configured to provide an error signal and an output signal. The error signal indicates one or more modulation errors. The output signal is a modulated version of the input signal that has been corrected using the adaptive signal to mitigate the one or more modulation errors.

In a method for the determination of the 3D coordinates of an object (2), a pattern is projected (1) onto the object (2) and the pattern reflected by the object (2) is taken (3) and evaluated. To improve such a method, a pattern is projected onto a first part region (12) of the object (2) in a first step and the pattern reflected by this part region (12) of the object (2) is taken. In a second step, a pattern is projected onto a second part region of the object (2) and the pattern reflected by this part region of the object (2) is taken. The patterns taken are evaluated.
摘要:
In a method for 3D digitization of an object (1), a plurality of camera images of the object are recorded and assembled to determine the 3D coordinates of the object. To improve such method, pictures are taken from the object (1), from which 2D feature points (11, 12, 13; 21, 22, 23) of the object (1) are determined. The 3D coordinates of the 2D feature points are determined. The 2D point correspondences (32, 32, 22) between the 2D feature points of a picture and the 2D feature points of another picture are determined. Several of these 2D point correspondences are selected, and an associated 3D transformation is determined. The quality of this 3D transformation is determined with reference to the transformed 3D coordinates of the 2D feature points. Valid 3D feature points are determined therefrom. For assembling the camera images of the object (1), the 3D coordinates of the valid 3D feature points are used.
