An optical system has an optical image projected on an analog memory, such as a CCD array, generating analog charge signals in the analog memory. The analog charge signals are processed with an analog to digital converter to generate digital information. The digital information is processed with an integrated circuit frequency domain processor to generate frequency domain information. The frequency domain information can be stored in an output memory and can be communicated to a remote location. An image can be displayed in response to the stored analog image information and in response to the frequency domain information. A machine can be controlled in response to the frequency domain information.

A filtering system is provided for acquiring and processing signals using a sampled filter for signal separation and signal enhancement; such as for determing locations, distances, and times in a geophysical exploration system. Signature signals permit mixing and seperation with sampled filters, such as for sharing common circuitry and for increasing the amount of acquired information. A sampled filter, such as a digital correlator, is provided for generating high resolution output data in response to low resolution input data processed with low resolution computation circuits. A real-time time-domain correlator is provided with single-bit resolution computational elements to provide improved correclation filtering. A high speed real-time correlator is provided to enhance signals with copositing-after-correlation and with correlation using a plurality of correlation operators.

A filter display system is provided for displaying filtered information. Input signals are multiplied by reference signals and summed to generate filtered signals for display. In an on the fly processing configuration, an input signal sample is processed in response to a plurality of reference samples before processing of other input signal samples. Various memory configurations are used to store signal samples; including RAMs, ROMs, and CCD memories. Processing is performed with various resolutions, including single-bit sample processing and multi-bit sample processing. Processing gain is used to provide processed signal samples having resolution better than the resolution of input signal samples. A display is provided that iteratively improves the displayed information as the filtering progresses. A pipeline configuration uses hardware for progressive processing of signal samples. An iterative configuration is implemented with a computer processing signal samples in iterative form. A hardware configuration uses address counters to process samples. Processing in response to a display synchronization signal provides synchronization between a processor and a display.

A high precision transducer and a system related thereto are provided for achieving high precision in an efficient, economical, and small size configuration. In a preferred embodiment, an optical position encoder transducer utilizes an optically sensed code wheel in combination with a vernier optical split to achieve high precision. Code wheel positions are sensed photo-optically to provide the most significant bits of the encoder position number. Optical slit position is sensed photo-optically to interpolate between disk code positions and to provide a high precision vernier to generating the least significant bits of the encoder output number. Anti-ambiguity circuitry resolves ambiguity between code wheel positions, vernier positions, and alignment. An array of photosensors provides enhanced precision and economy. Systems utilizing such transducers include digital readout systems, machine control systems, and data logging systems.

Memory technologies for storing filter samples include RAMs and CCDs. Adaptive memory capability and memory servo capability improve memory characteristics. In a RAM embodiment, a detector is used to detect a memory address condition and to control the memory and the memory address register in response thereto. In a CCD embodiment, a detector is used to detect a memory reference signal and to refresh the memory signals in response thereto. Improved memory refresh, memory performance, and memory capacity enhance system characteristics. Improved memory architecture provides advantages of increased speed, lower cost, and efficiency of implementation. Information stored in memory can be scanned out at a rate greater than the addressing rate associated with the memories. This permits higher speed operation with lower cost memories. Use of an output buffer, such as a FIFO, permits normalization of memory clock rates.
