SIMPLE DEVICE FOR SMALL DIMENSION MEASUREMENT USING CCD SENSOR

Jan Fischer, Vladimír Haasz, Tomáš Radil

Abstract

The dimension of a measured object is determined from its shadow projected on a CCD sensor. A light source of parallel beams is usually applied in this case. To achieve such light source quality, an optical system with lenses has to be used. It increases its dimension and its price. The published solution applies one or several point light sources and a CCD sensor without lens. It enables to reduce both a dimension and a price of device.
