A Circuit Design of Spectrum Signal Acquisition with Low Noise and Wide Dynamic

Abstract:

Using spectrum signal acquires the information of printing colors, it has the advantages of fast response speed, wide color gamut range, high resolution, etc. And it is the key techniques in the print ink control. In this paper, it introduces a broadband and large dynamic spectrum signal acquisition circuit. It uses micro photoelectric diode array spectrum sensors, processing analog spectra signal with broadband low noise amplifier. It realized the low noise large dynamic performance through analog-to-digital converter (A/D), signal preprocessing and the optimal design of power circuit. Its spectral wavelength resolution is 0.3 nm, range from 15 to 400 lumens (lm) illumination spectrum signal acquisition, within the scope of the design of the system signal-to-noise ratio to 45 dB.
