| 摘要 |
Optoelectronic system composed of a light generator fitted with colour filters and with a diaphragm controlling the quantity of light emitted; this light, transmitted by a bundle of optical fibres, illuminates the operating field where, under the best conditions, the preparation, application and polymerisation of light-polymerisable products may be performed (followed). The colour filters facilitate, or on the contrary prevent, this polymerisation function and their choice by the operator is slaved to a correction of the RGB signals, which improves the quality of the image obtained in all cases of use. Objectives (lenses) of the "endoscope" type allow axial or lateral imaging (picture-taking), obliterating, if necessary under the conditions of use, the "mirror effect". <IMAGE> |
