Abstract: A photonic integrated circuit (PIC) spectrometer for sensing the spectroscopic signature of airborne molecules, comprising a dispersive element to separate the spectral information spatially, and a tuning mechanism for said dispersive element to convert the spectral information to time-dependent information. The approach allows the PIC spectrometer to have a single (or a few) output pin(s), enabling sensing of the environment with a simple packaged chip that is compact, lightweight, energy efficient and low cost, making it suitable for platforms that have a small form factor, a small power budget, and are cost sensitive, such as mobile devices.

Abstract: Methods and systems for performing spectroscopic measurements of semiconductor structures including ultraviolet, visible, and infrared wavelengths greater than two micrometers are presented herein. A spectroscopic measurement system includes a combined illumination source including a first illumination source that generates ultraviolet, visible, and near infrared wavelengths (wavelengths less than two micrometers) and a second illumination source that generates mid infrared and long infrared wavelengths (wavelengths of two micrometers and greater). Furthermore, the spectroscopic measurement system includes one or more measurement channels spanning the range of illumination wavelengths employed to perform measurements of semiconductor structures. In some embodiments, the one or more measurement channels simultaneously measure the sample throughout the wavelength range. In some other embodiments, the one or more measurement channels sequentially measure the sample throughout the wavelength range.

Abstract: An inspection device includes: an illumination device that irradiates an object with near infrared light; a spectroscope that disperses reflected light from the object irradiated with the near infrared light; an imaging device that takes a spectroscopic image of the reflected light dispersed by the spectroscope; and a processor. The processor: obtains spectral data at a plurality of points on the object based on the spectroscopic image obtained by the imaging device; selects, as typical spectral data representing the object from among the spectral data at the plurality of points, one of: spectral data in which a luminance value in a predetermined wavelength is a median value; and spectral data in which a summation of luminance values in a predetermined wavelength range is a median value; and performs a predetermined analysis for the object based on the typical spectral data and detects a different type of object.
