Photoelectric imaging system based on low-dimensional quantum structure photoelectricity sensor reading circuit

Abstract

The invention discloses a photoelectric imaging system based on a low-dimensional quantum structure photoelectricity sensor reading circuit. The system comprises a low-dimensional quantum structure photoelectricity sensor reading circuit module, an ARM (Advanced RISC Machines) module and a general-purpose computer imaging software module. Hardware modules are connected in a bus mode, the ARM module outputs parallel control signals, receives status signals output by the reading circuit module and collects serial data, the ARM module communicates with a general-purpose computer in a universal serial bus (USB) mode, and the imaging software module runs in the general-purpose computer, obtains data through drivers, processes voltage value uploaded by lower computers of each pixel of a photoelectricity sensor and displays the corresponding gray value. The system presents gray images of vision corresponding to the photoelectricity sensor on the general-purpose computer, and provides convenience for measurement, adjustment, application and development of the photoelectricity sensor.

Description

technical field [0001] The invention relates to the technical fields of circuit design, automatic control, communication, measurement, instrumentation, etc., and is a photoelectric imaging system for collecting and displaying circuit data read out by a photoelectric sensor with a low-dimensional quantum structure. Background technique [0002] Photoelectric sensing technology has been widely used in all aspects of production and life, among which infrared sensing technology is particularly rich in content - from the initial military application to modern industrial measurement and control, medical detection, disaster prevention and other fields. In terms of sensing device materials, charge-coupled device image sensors (CCDs) are the dominant players in conventional imaging readout, but complementary metal-oxide-semiconductor (CMOS) technology is , Easy to integrate functional circuits and other advantages continue to develop, and become a readout imaging technology that can ...

Problems solved by technology

[0004] The above-mentioned DAQ built by independent modules is obviously too fragmented, which is not conducive to the realization of low power consumption, easy debugging and reliability of the system

The most widely used solution in the market is the field programmable gate array (FPGA) external analog-to-digital converter (ADC), which has not fully realized the high integration of modules; the communication with the computer still uses a general-purpose synchronous / asynchronous serial receiver / transmitter ( USART) interface, the data transmission rate is too small, or directly use the LCD screen display as a portable device, the signal processing capability and versatility are not high
