    Abstract: PROBLEM TO BE SOLVED: To provide an implantable sensor and spectroscopic technique for exact in vivo measurement of body fluid constituents. SOLUTION: An infusion pump system for monitoring the concentration of at least one chemical constituent of body fluid in a mammal and delivering medication to the mammal is provided and the system comprises: (a) the implantable sensor adapted for determining the concentration of the chemical constituent of the body fluid in the mammal using in vivo spectroscopy; and (b) a pump module connected to the sensor for dispensing doses of medicine in response to the concentration of the chemical constituent output from a processor. The sensor includes; (i) a source of light which emits at a plurality of different wavelengths, at least one of the wavelengths being in the infrared region; (ii) a detector for detecting light emitted from the source and outputting a signal which contains spectra of the body fluid at each of the plurality of different wavelengths, so that the light output from the source is received by the detector after interaction with a body fluid, and that light from each of the plurality of different wavelengths form a substantially collinear optical path through the fluid with respect to one another; and (iii) the processor for analyzing the signal and the spectra, and determining therefrom the concentration of the chemical constituent of the body fluid.

    Abstract: Disclosed are a device and method for detecting a subsurface defect of an optical component. According to the device and method, a spectral confocal technology, a laser scattering technology and a laser-induced ultrasonic technology are combined, excitation laser and detection laser are simultaneously focused to different depths of the optical component through a dispersion lens set, the excitation laser generates a transient thermal expansion effect on a subsurface of the optical component, the detection laser is used for observing and analyzing ultrasonic vibration of the subsurface defect under an action of the thermal expansion effect, and spatial distribution information and scattered spectral information of scattered light at a position of the subsurface defect are acquired by the spectral confocal technology. The device and method are suitable for nondestructive testing of a finished product of an ultra-precise optical component with a strict requirement on the subsurface defect.
