摘要： Error introduced by analog to digital conversion of a set of laser pulses can be reduced by shifting the clock reference time associated with the firing of the laser pulse. A timing offset module shifts the timing reference of each laser pulse. Digital codes generated by the ADC from the received signals are realigned and summed eliminating systematic error introduced by clock driven operations of the ADC. A comparison of the total ADC output of detected laser pulses over a select number of clock intervals enables a return signal to be distinguishable over the systematic error.

摘要： A system for automatically capturing an image of a moving vehicle and recording data parameters, such as date, time, speed operator, location, etc. on the image. A capture window that comprises a predetermined range of distances of the system from the moving vehicle can be set by the operator so that the image of the moving vehicle is automatically captured when it enters the capture window. The capture window distance can be entered manually through a keyboard or automatically using the laser speed gun. Automatic focusing is provided using distance information from the laser speed gun. A database is included to allow the user to search for specified parameters. Data records can be flagged for issuance of citations. A separate office unit is disclosed for retrieving and sorting data records so that field units are not occupied with such tasks. The office unit can be separately connected to licensing databases to retrieve information for issuance of citations.
