ABSTRACT:
Disclosed in an optical distance measuring apparatus using an observation lens and at least one reflector. Thanks to the use of reflectors the whole size of the apparatus reduced at least one half of a conventional distance measuring apparatus, still assuring the same exactness as the conventional apparatus in measuring a distance.
