摘要： An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4π radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.

摘要： In the optical deflector, the mean width of profile elements of a cross section of the deflection surface in the sub scan direction is set to be less than the spacing between spots of the light beams formed in the sub scan direction of the deflection surface. This makes it possible to prevent a variation in the size and shape of the spots of the light beams deflected by the deflection surface due to the undulation (unevenness) of the deflection surface. As a result, it is able to suppress a decrease of the granularity of images and form images with high quality.
