  • Laser scanning system
    Patent number: 5497184
    Abstract: A laser scanning system in which a laser beam is emitted by a laser source and repeatedly deflected by a deflector, such as a polygon mirror. A photo sensor is provided to detect the position of the deflected laser beam. The photo sensor and the laser source are mounted on a common support member so that the laser beam, deflected by the polygon mirror, directly enters the light receiving portion of the photo sensor. Optionally, a reflection mirror is provided such that the deflected laser beam is reflected by the reflection mirror and further deflected to the photo sensor by the polygon mirror.
