Abstract:
With an interference light prevented from occurring by inserting a shutter into an optical path on a reference light side prior to an observation by means of an optical scanning probe using light such as a low-coherency light source, a reference member is moved by a drive device on an observation optical path side by the optical scanning probe to set the reference member to the focal point position of a condensing optical system so as to maximize the output of a photodetector, and then the shutter is opened to move and set a mirror position on the reference light side so as to maximized the output of a light detecting means, whereby it is possible to simply and smoothly set an optical scanning type observation device so as to be kept in excellent optical characteristic conditions.

PROBLEM TO BE SOLVED: To simply manufacture a living-tissue prosthesis which enables the distribution of a porosity to be freely designed, and which enables a blood flow to rapidly occur even inside. SOLUTION: This body-tissue prosthesis manufacturing apparatus 1 comprises: a stage 6; a polymer dispenser 3 which can eject a pore forming member, composed of a polymer 2, in a prescribed pattern onto the stage 6 in such a manner as to have a certain height; a first movement mechanism 6 which two-dimensionally and relatively moves the polymer dispenser 3 in a horizontal direction with respect to the stage 6; a filling device 5 which infills aqueous foamed slurry 4, containing impalpable powder of calcium phosphate-based ceramics, up to the same height as that of the pore forming member between the pore forming members, so as to form an aqueous foamed slurry layer; and a second movement mechanism 6 which makes the polymer dispenser 3 and the filling device 5 ascend relatively to the formed aqueous foamed slurry layer.

PROBLEM TO BE SOLVED: To enable an experimental animal to be observed over a long period without straining the experimental animal while keeping a healthy state. SOLUTION: The subject window member 1 for observation comprises an optically transparent biocompatible material, and is formed into a plate or film shape to be stuck to an internal texture 3 at the region from which the epidermis 6 of the experimental animal is removed. The experimental animal having the observing window 7 obtained by attaching the window member 1 for the observation and attached to the region from which the epidermis is removed is also provided. Preferably, the window member 1 for the observation has flexibility, and also has an attaching part 4 to the experimental animal 2. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To dispense with the positioning of object lens performed at every time of observation. SOLUTION: An object lens insertion fixture 51 is positioned and fixed on the skin W2 of an observation object W together with a base part 54 and a fixation ring 62. The object lens insertion fixture 51 is further provided with an insertion hole 52 for inserting an object lens unit 23. The object lens unit 23 is inserted into the insertion hole 52 until the surface 45 of a frame part 41 is abutted on the flat plane 56 of the insertion hole 52 and is fixed by a screw 60 screwed into the base part 54. Therefore, the object lens unit 23 is positioned and fixed on the observation object W via the object lens insertion fixture 51. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide an endoscope constituted so as not only to variably set the magnification of an endoscopic image but also to perform the focal adjustment of a co-focal image. SOLUTION: An image pickup unit 36 having an optical system for endoscopic observation and an optical system 37 for microscopic observation for microscopically observing the observation region of a subject are mounted in the distal end part 18 of a zoom endoscope 1. A second lens group 36b, which functions as the zoom optical system of the optical system for endoscopic observation, and a mirror frame 37d, which holds the object optical system 37c of the optical system 37 for microscopic observation, are moved by a linear actuator moving member 40 for focal adjustment and a linear actuator moving member 41 for adjusting an image angle both of which use piezoelectric actuators or the like arranged on the same axis before and behind as drive sources. Since both linear actuator moving members 40 and 41 are arranged on the same axis before and behind, the space saving of the distal end part 18 of the endoscope can be realized.

PROBLEM TO BE SOLVED: To provide an optical image taking-in device in which an image is formed by controlling a deflection angle in a constant state. SOLUTION: An optical fiber 4 which transmits light emitted from a light source is penetrated in an optical scanning probe, the light emitted from the end face 4a of the optical fiber 4 is reflected on a fixed mirror 15, reflected on a mirror part 17 in which the deflection angle of a scan mirror device 16 is variable, passes through a condenser lens 18, and a test piece is scanned with the light two-dimensionally. In this case, the back face of the mirror part 17 is radiated with the light emitted from an optical fiber 29 arranged on the back side of the scan mirror device 16 and the spot of the reflected light is received with a PSD sensor provided on a substrate face opposite to the mirror part 17, the deflection angle is detected by detecting the location of the spot and deflection angle is controlled to be kept constant.
