| titleOfInvention | Data acquisition and control system for a precision instrument, e.g. a spectrometer |
| abstract | An embedded data acquisition and control system for precision instruments is disclosed. It provides a synchronization of stepper motor position and analog-to-digital converter, in order to minimize the wavelength shift error due to the asynchronous. The controller synchronizes the event of reading the A/D converters with each stepper motor position. According to another future of the invention, a position encoder is coupled to the stepper motor shaft for archiving in an actual position feedback. Because the embedded controller has the position feedback, it can initiate the next step command as soon as the position feedback reaches its target. The step rate is increased by reducing the time delay that was set by conservative value as indicated in the open loop control mode. A further future of the invention provides optical isolation to minimize motor noise. |
