Abstract
An apparatus for measuring distances includes a lens module, a light sensor, and a calculation module. The lens module is used for imaging an object to be measured. The lens module has a focal plane which is non-vertical to the light axis thereof. The light sensor is used for receiving the image of the object through the lens module, and generating a corresponding signal accordingly. The calculation module is used for calculating the distance of the object based on a high frequency part of the signal. A relative method for measuring distances is provided as well.
