Patent ID: 8810795

Claim:
An optical detection system, including: a light source unit, used to provide light; a control unit, including: a first mirror, used to receive light; a first one-dimensional off-axis parabolic mirror; a second one-dimensional off-axis parabolic mirror; a cylindrical lens, disposed between the first one-dimensional off-axis parabolic mirror and the second one-dimensional off-axis parabolic mirror; a second mirror; and a triangle mirror, having a first reflection side and a second reflection side; and a detection unit; wherein, the first reflection side of the triangle mirror receives light from the light source unit and directs the light into the first mirror, the first mirror directs the light into the first one-dimensional off-axis parabolic mirror, and the first one-dimensional off-axis parabolic mirror directs the light into a cylindrical lens, and the cylindrical lens directs the light to the second one-dimensional off-axis parabolic mirror; the second one-dimensional off-axis parabolic mirror directs the light to the second mirror; the second mirror then output the light; the second reflection side of the triangle mirror receives light from the second mirror and directs the light into the detection unit, and the detection unit detects the light coming from the control unit to output a signal.
