Excuse me, which a player know the laser rangefinder system based on single chip the graduation design to do?

Design requirements

1. Basic requirements
(1) the measuring range 0.10-5.00 M;
(2) can steadily display measured results;
(3) can differ according to the length of the distance of the frequency of sound. Problems added:
A, design task
Simulation design and production of a laser rangefinder system.
Second, the design requirements
1. Basic requirements
(1) the measuring range 0.10-5.00 M;
(2) can steadily display measured results;
(3) can differ according to the length of the distance of the frequency of sound.
2. Play a part
(1) can be applied to the industrial field position monitoring;
(2) can be used for liquid level, well depth, length of pipe of the survey;
(3) speech function;
