A disadvantage of optical holog raphy has been that the sensitivity to movement and the coherence requirements for hologram recording ordinarily lead to rather large and massive systems and/or lasers. In this paper we describe a portable hologram micro scope which uses a small, reliable pulsed ruby laser light source to overcome this disadvantage. This instrument was designed to record images of rough, diffusely reflecting surfaces with a resolution of 5 pm or better.
