PHOTO DETECTING SENSOR HAVING MICRO LENS ARRAY

摘要

An objective of the present invention is to provide a light detection sensor having a micro-lens array which can prevent optical loss in a surrounding area. The light detection sensor having a micro-lens array comprises: a light detection unit to detect an optical signal entering an effective sensing area for light detection; an optical unit installed on a front end of the light detection unit to allow the optical signal to propagate therethrough; and a micro-lens array installed between the optical unit and the light detection unit to condense the optical signal propagating through the optical unit into the effective sensing area for light detection of the light detection unit.
