Design of a low-cost and high-dynamic USB3.0 domestic ultraviolet industrial camera based on field programmable gate array

A CMOS (Complementary Metal Oxide Semiconductor) industrial camera based on EFINIX FPGA (field programmable gate array) was designed to solve the shortage of chips for high-performance industrial cameras in China. GLUX9701BSI (Gpixel), SCB13H4G160AF-11MI (UnilC), and CH569 (WCH) are applied as an image sensor, a memory module, and a data output module respectively. The overall structure of the camera is illustrated systematically and specifically as well as the design of the hardware circuit. The experimental results show that images can be uploaded to the host computer via USB 3.0 interface stably at high speed. It is a monochrome camera in visible light equipped with an all-pass filter, while it is an ultraviolet (UV) camera in UV light equipped with a low-pass filter. The camera supports a high dynamic range of 79.9 dB and an ultra-wide spectral response of 200-1100 nm. But the power consumption of the camera is only 1.3 W. The key technical specifications have reached or exceeded the overseas products of the same kind, but the price is only 40% of similar products abroad. The design realizes the comprehensive China core of high-speed industrial cameras, breaks the bottleneck of a long-term dependence on imports for industrial cameras, and relieves the shortage of chips for industrial cameras in the domestic market.
