Laser Beam through Two Points by Turning Two Mirrors

​
slope of mirror 1
-0.87
slope of mirror 2
-0.82
This Demonstration shows a step-by-step procedure for directing a laser beam through two points by turning two mirrors. The vertical distances between the initial beam and the points 1 and 2 are denoted
d
1
and
d
2
.

Details

These are the steps to make the beam pass through the two points by rotating the two mirrors.
0. The beam does not pass through either point
(
d
1
=7;
d
2
=3)
.
1. Turn mirror 1 to make the beam pass through point 1
(
d
1
=0,
d
2
=20)
.
2. Turn mirror 2 to make the beam pass through point 2
(
d
1
=5,
d
2
=0)
.
3. Repeat steps 1 and 2 sequentially as needed.
For example:
1.
(
d
1
=0,
d
2
=12)
2.
(
d
1
=3,
d
2
=0)
1.
(
d
1
=0,
d
2
=7)
2.
(
d
1
=2,
d
2
=0)
1.
(
d
1
=0,
d
2
=3)
2.
(
d
1
=1,
d
2
=0)
1.
(
d
1
=0,
d
2
=2)
2.
(
d
1
=1,
d
2
=0)
2.
(
d
1
=0,
d
2
=0)
The beam now passes through the two points.
