The invention relates to a method and a system for correcting depth errors caused by different types of optical aberrations in depth images generated from depth from focus systems.

The present invention provides a distance measuring device for measuring a distance, comprising a light emitting unit for emitting a measuring light beam toward an object to be measured, and a photodetection unit for receiving a reflected measuring light b...

A deflection unit includes a transmission lens (7) and an actuator. To deflect the transmission beam, the transmission lens is periodically steered by the actuator. A detector has a detector lens (8), which is spaced apart from the transmission lens, so th...

The present invention relates to a light wave rangefinder for measuring a distance to an object of measurement by means of light reflected from the object of measurement without using a prism, and particularly to provision of a light wave rangefinder that ...
