Patent number: 9080974Abstract: Provided is an observation device and a method of observing capable of clearly obtaining information relating to a boundary part where a medium inside an observation object changes. An observation device (1) is a device for observing an observation object (2) including a sensitivity factor in which a dipole moment changes by sensing an electromagnetic wave (31). An output part (11) outputs the electromagnetic wave (31) and the dipole moment of the sensitivity factor included in the observation object (2) is changed by the electromagnetic wave (31). A detector part (12) detects, of the electromagnetic wave (31) outputted from the output part (11), a signal electromagnetic wave (33) which comes through the observation object (2) and a reference electromagnetic wave (32) which bypasses the observation object (2).

Patent number: 8121663Abstract: In one aspect, the invention features a method and device for measuring blood concentration of a substance such as glucose in the aqueous humor by illuminating the aqueous humor with a light source at a frequency that is absorbed by the substance to the measured, and then sensing photoacoustically generated sound waves originated within the aqueous humor as a consequence of illumination by the light source. The blood concentration can be estimated from the amplitude of the sound waves received. The method may be combined with other optical techniques for glucose measurement and/or with optical or ultrasonic techniques for topographic mapping of eye structures.Type: GrantFiled: October 11, 2007Date of Patent: February 21, 2012Inventors: Gholam A.
