摘要:
An optical system is provided having an analog image memory, an analog refresh circuit, and an analog converter. An optical image is projected on an analog memory, such as a CCD array, generating analog image signal samples in the analog memory. The analog charge signal samples can be shifted in the array and can be processed with an analog to digital converter to generate digital signal samples. The digital signal samples can be processed with a digital processor, such as a digital transform 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 signal samples or in response to the frequency domain information.

Provision is made for a dynamic memory with a memory refresh arrangement. Memory refresh is synchronized with computer control signals to minimize contention or conflicts with computer operations and to share control circuitry. Improved control system architecture, computer architecture, and memory architecture are provided that are particularly suitable for operator interaction, integrated circuit data processors, and dynamic memories.

Illumination control systems implemented with illumination amplifiers, such as liquid crystal devices, are provided. Heat transfer devices remove heat, such as heat caused by the high intensity illumination, from the illumination amplifier. The illumination amplifiers can be implemented in either transmissive or reflective modes. In a reflective mode, illumination can be reflected from a front side and heat can be removed from a back side of the illumination amplifier. Color is provided, such as generating multiple channels of different color images and projecting the different color images to generate a multicolored image.

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.
