Survey system
First Claim
1. A survey system, comprising:
- a target provided with a recursion reflector for reflecting light in a direction from which the light comes; and
a survey apparatus provided with an automatic collimating device for automatically coinciding a collimation axis of said recursion reflector with that of a telescope,wherein said target is provided with a guide light transmitter for emitting guide light showing the direction of the guide light transmitter, andsaid survey apparatus includes collimation preparing means having a direction detector for detecting the direction of said guide light transmitter by receiving said guide light and turning said telescope toward the direction of said recursion reflector on the basis of an output signal from said direction detector before starting said automatic collimating device; and
said guide light transmitter scans a fan beam that is wide in a width direction and narrow in a thickness direction in a direction differing from the width direction as guide light.

Abstract
A survey system for transmitting guide light for instructing the direction of a target, the guide light having a wide range with small power. The survey system includes a target having a recursion reflector for reflecting light and a survey apparatus having an automatic collimation device for automatically coinciding the collimation axis of the recursion reflector with that of a telescope. The target includes a guide light transmitter for emitting guide light and scans a fan beam that is wide in the horizontal direction and narrow in the vertical direction in the vertical direction as guide light. The survey apparatus includes a direction detector for receiving guide light and detecting the direction of the guide light transmitter and also includes a collimation preparing device for turning the telescope roughly to the recursion reflector based on an output signal from the direction detector prior to commencing the automatic collimation.
