    摘要: This application describes a medical device (230) for obtaining optical tissue properties of a target material. The medical device (230) comprises an elongated body (231) having a longitudinal axis (232) and an optical fiber being integrated within the elongated body (231). The optical fiber has a second fiber end (242, 242a, 242b), which is arranged at a side wall (233) of the elongated body (231) and which provides a lateral field of view with respect to the longitudinal axis (232). According to an embodiment many optical fibers are integrated each having an optical outlet (242, 242a, 242b) around the elongated body (231). Using the outlets (242, 242a, 242b) to do diffuse optical tomography and also use optical fibers to do an optical inspection, one can get information on the presence of tumors in a volume around the medical device (230) and a tissue characterization in the vicinity of the medical device (230). Thereby, an optical biopsy may be carried out, wherein no real tissue is removed. According to another embodiment an optical detection system is integrated into a real biopsy needle (330) allowing inspection and taking real biopsy simultaneously.

    摘要: An optical scanning device for scanning an optical record carrier. The optical scanning device includes: a radiation source system (661; 761); an optical element (1; 101; 201; 301) comprising a first fluid (A) and a second fluid (B; C) separated from each other by a fluid meniscus (16; 116, 138; 216; 316) having an adjustable configuration; and a control system (20; 120; 220; 320) arranged to adjust the fluid meniscus configuration to introduce a first type of wavefront modification. The first type of wavefront modification causes the radiation beam to be redirected from an input radiation beam path (2; 102; 244; 348) onto one of a plurality of output radiation beam paths (24, 26; 140; 246; 350) which each have a different angular displacement (α, β, γ, δ, ∈) from the input radiation beam path. The control system is further arranged to adjust the fluid meniscus configuration to introduce a second type of wavefront modification. The second type of wavefront modification is arranged to compensate a wavefront aberration of the radiation beam, the compensated wavefront aberration being adjusted in accordance with the angular displacement.
