Abstract
This invention concerns a light wave distance meter which comprises a telescope unit supported on a framework such that the unit can rotate about a horizontal axis. This unit being provided with a telescope having a target in its line of sight, with an analog photoemitter which directs modulated light emitted by an optical device at the target, and with an analog photodetector which receives modulated light reflected from said target so as to measure the distance to said target.
Claims3
A distance measuring device comprising:
- a supportable telescope unit including a case, said case including a telescope, first and second chambers on one side of said telescope and third and fourth chambers on the opposite side of said telescope;
- a target;
- analog photoemitter means in said second chamber for directing modulated light toward said target in response to a first signal;
- analog photodetector means in said third chamber for receiving modulated light reflected from said target and generating a second signal in response thereto;
- processing means in said first chamber for determining the distance to the target based upon said first and second signals;
- and
- power supply means in said fourth chamber for supplying power to said analog photoemitter means, analog photodetector means and said processing means.
