An image sensor includes a rod lens array. The rod lens array includes a plurality of rod lenses which are placed within a frame. The frame has an engagement part to secure it to a housing of the image sensor. The engagement part can be a groove in the frame which is secured to the housing by a ridge in the housing. In an alternative, the engagement part can be flanges on the frame which are engaged with shoulders in the housing. No adjusting mechanism for the array such as an adjustment screw, is needed.

An acousto-optic deflector is supplied with a beam of laser light and driven in a parallel relationship with a plurality of high frequency signals to produce a plurality of diffracted deflected beams of laser light. The high frequency signals have phases independently controlled so as to prevent the resultant combination of the high frequency signals from having an excessively high peak-to-peak amplitude.
