Applying holography as a technique of measuring the size distribution of micro bubbles and particles in liquids brings up the possibility of direct observation of micro objects, and thus knowing their exact shape and size. The present technical note deals with the design of a holocamera, and its calibration. In the present system, a ruby laser is used for producing the coherent, linearly polarized light source 0.6943 micrometer wavelength for the hologram recording, and a CW He-Ne laser 0.6328 micrometer - wavelength is used as a light source for the reconstruction process. More detailed description of the instrumentation will be given later.
