A new assembly method using guide-frames is described for easy construction of compact and practical free-space optical modules. Basic performances of this method are examined by assembling a two-dimensional optical fiber collimator, which is used to free-space optical telecommunications systems. Also, the method is applied to assemble a digital discrete correlator (DDC), which is a fundamental part of freespace optical computing systems. It is shown that a multistage optical system can be constructed simply by stacking the several optical functional blocks, and these compact modules do not need an optical bench, and they are one tenth of conventional optical system volume. It is demonstrated by experiments that our proposed assembly method can be utilized for these optical modules.
