摘要： A prism is attached to a refractive index dispersion lens by inclining the incident plane of the prism by a prescribed angle with respect to the end face of the refractive index dispersion lens and filling adhesive therebetween. In this way, the amount of light reflected from the bottom plane of the prism decreases in accordance with the angle of inclination of the incident plane, and the interference signal formed by the reflected light from the bottom plane of the prism, and the reflected light of a reference beam therefore weakens and the image signal decreases. Consequently, distinguishing between the image signal and the image signals produced by reflected light from the measurement subject is facilitated.

摘要： Methods of optimizing optical alignment in an optical package are provided. In one embodiment, the optical package includes a laser diode, a wavelength conversion device, coupling optics positioned along an optical path extending from the laser diode to the wavelength conversion device, and one or more adaptive actuators. The method involves adjusting the optical alignment of the wavelength conversion device in a non-adaptive degree of freedom by referring to a thermally-dependent output intensity profile of the laser diode and a thermally-dependent coupling efficiency profile of the optical package. The adjustment in the non-adaptive degree of freedom is quantified such that, over a given operating temperature range of the optical package, portions of the coupling efficiency profile characterized by relatively low coupling efficiency offset portions of the output intensity profile characterized by relatively high laser output intensity and portions of the coupling efficiency profile characterized by relatively high coupling efficiency offset portions of the output intensity profile characterized by relatively low laser output intensity. Additional embodiments are disclosed and claimed.
