OptiCheck™ Technology
The OvationONS sensors use Cypress Semiconductor’s
patented OptiCheck technology — a fundamentally different
approach to laser navigation sensing. Instead of image capture
and correlation, OptiCheck uses an “Optical Checkerboard” or
array of light-sensitive elements connected in a patented, 2D
comb detector configuration[1]. The outputs of the detector are
amplified and combined in a unique arrangement to form four
data outputs that completely describe the motion of the sensor.
These four outputs are digitized and sent to a small digital signal
processor to generate x and y location displacement data.
Figure 1 shows the interconnection of the comb detector
elements and the resulting four outputs.

There are three key advantages to the OptiCheck approach:
■ First, power consumption does not increase with an increase
in tracking speed. OptiCheck requires only four data inputs to
calculate x and y displacement, compared to the hundreds of
inputs typically required for image correlation. OptiCheck
therefore provides a much more efficient calculation. This
increase in efficiency means the signal processing blocks have
a negligible impact on power consumption, resulting in a
system where current draw is nearly independent of speed.
■ Second, tracking speed is independent of resolution.
OptiCheck’s processing requirements are independent of
sensor resolution. This enables simpler and lower cost scaling
for products that require both high speed and high resolution
tracking performance.
■ Third, the unique signal processing method employed by
OptiCheck sensors enables continuously variable native
resolution in the x and y directions independently. This unique
capability offers application designers immense flexibility and
freedom.
