Abstract

Optical Coherence Tomography (OCT) applications can be divided into biomedical and industrial, the latter covering non-destructive testing of non-reflective materials (e.g. optical glass) or for profilometry of metallic surfaces. Irrespective of the areas mentioned above, it is important to translate the technology from lab to clinical and industrial environments, depending on the case. This paper presents handheld probes with 1D galvoscanners developed in our groups to achieve this goal. These probes have been designed to be as simple, light weight, and low-cost as possible. Their optomechanical construction is described in different variants. Advantages regarding galvoscanners use are discussed, as compared to probes equipped with MEMS. The optomechanical aspects are completed with a discussion on optical design and on other scanning systems that may be utilized in such probes. Several applications of the probes developed are presented, such as in optical metrology.
