Optical navigation devices and associated methods |
摘要 |
The imaging device has an imaging surface and a sensor, wherein the imaging surface is illuminated and reflects at least some of the illumination to the sensor to detect an image. The imaging device has a width and an optical path passing therethrough, wherein the optical path exhibits distortion as a result of the width of the device and the nature of the optical path. The imaging device includes an optical element which in use compensates for the distortion by generating a magnification profile across a tangential plane of the device at the sensor.
