For making complex optical system meet the design requirement
such as the space camera used in remote sensing and UVX lithophotography
especially for off-axis all-reflecting optical system
alignment technology is so necessary. In this paper
a method is presented. Based on the ideas of linearity instead of non-linearity and difference quotient instead of differential quotient
a mathematical model for computer-aided alignment is proposed. This model included the characteristics of the optical system
wavefront difference of its exit pupil and its misalignment of the misaligned optical system. Then comparing self-compiled software with alignment package of CODE V
as a result
this self-compiled software is much more valid than alignment package of CODE V. For a large aperture
long focal length and off-axis three-mirror optical system
computer-aided alignment is successful. Finally
the wavefront error of the middle field is 0.094 waves RMS and the wavefront error of +0.7 field is 0.106 waves RMS and the wavefront error of -0.7 field is 0.125 waves RMS at =632.8nm are obtained.

We study insertion losses of optical switch when the laser beam is propagating during the free space between two single mode fibers (SMFs) and the related assemblage challenges
Then a new packaging structure is developed for the hybrid-integration of free-space MOEMS (micro-opto-electro-mechanical systems) chip with a silicon micromachined submount to improve alignment accuracy. The submount is designed to accommodate various free-space MOEMS chips with minimal active optical alignment
thus reducing the packaging cost. The silicon submount has a central recess to place the MOEMS chip in
sixteen V-grooves for optical fibers
and micropits for micro ball lenses
all bulk micromachined at the same time by a single anisotropic wet etching step. A corner compensation technique is employed to prevent erosion of the convex corners
where different geometries meet. Through this assembling method
the fiber
micro ball lens can be aligned preciously thus reduced lateral and angular misalignment between them. Then total insertion losses can be decreased.
