Abstract
An optical space communication apparatus such as an optical space communication transceiver comprises a plurality of modules which can be coupled and separated from each other. In the modules, the positions of optical elements are adjusted beforehand with respect to coupling reference portions of the modules which are to constitute a common reference at the time of coupling of the modules. As a result, the modules can be automatically positioned relative to one another at the time of coupling therebetween. Alternatively, one of the plurality of modules may have a stand reference portion having a predetermined positional relationship with its optical element and its coupling reference portion. The stand reference portion is coupled to the reference portion of the stand whose angle can be adjusted to thereby constitute the common reference.
