Patent ID: 8922860

Claim:
A method of defining a scan path using a scanning optical system to scan a beam spot formed by a light beam over one or more biosensors supported by a microplate, comprising: inputting to a multi-axis motion controller move commands associated with the scan path as defined by multiple axis comprising an x-baseline coordinate x 0 , a y-baseline coordinate y 0 , an x-direction oscillation amplitude x 1 , a y-direction oscillation amplitude y 1 , an oscillation frequency f and a phase φ; outputting from the multi-axis motion controller commanded positions for each of the multiple axes; receiving the commanded positions with a post-processor and generating therein parameterized commanded positions x and y defined the following equations where t is time and OSC is an oscillatory function: x=x 0 +x 1 ·OSC(2 π·f·t +φ) and y=y 0 +y 1 ·OSC(2 π·f·t +φ); and inputting the parameterized commanded positions x and y to a scanning optical system to cause the scanning optical system to deflect the light beam to scan the beam spot over the scan path.
