摘要： An optical system includes a micromirror array, conjugate to a sample and disposed in incident and/or return optical paths to/from the sample. Micromirrors in the array are imaged onto corresponding lateral locations on the sample. The micromirrors are modulated at unique assigned frequencies. Imaging optics produce a modulated image of the sample at a multi-pixel detector. The image is dispersed in one dimension by a spectrally dispersive element in the return optical path. The detector pixels produce time-varying electrical signals. Lock-in amplifiers or a Fast Fourier Transform module spectrally analyze the time-varying electrical signals. Signal amplitudes at the assigned frequencies determine how much light from a particular lateral location at the sample is present at each detector pixel. The signal amplitudes along the spectral direction, referenced to the lateral location, provide a wavelength spectrum of the sample at the particular lateral location.

摘要： A detection system includes a micromirror array, conjugate to a desired depth below the surface of a sample, in incident and/or return optical paths. The micromirrors in the array are modulated at unique assigned frequencies that can be within a single octave. An optical detector in the return optical path produces an electrical signal that can be spectrally analyzed to determine a sample reflectivity as a function of lateral location on the micromirror array. In a confocal configuration, signal amplitudes at the assigned frequencies, within the single octave, correspond to light rays striking the same micromirror twice, and represent light reflected from the desired depth. Signals at frequencies outside the single octave correspond to light rays striking two different micromirrors, which receive modulation at two different frequencies in the same octave and therefore heterodyne out of the octave, and represent light reflected from depths other than the desired depth.

摘要： A prism is configured to receive a collimated beam and propagate an internal beam that follows a path having multiple reflections inside the prism. The multiple reflections occur among an ATR face, a detector face, and a high-reflectance face of the prism. An angle between a surface normal of the high-reflectance face and a surface normal of the ATR face is equal to an angle between a surface normal of the detector face and the surface normal of the ATR face. The surface normals of the ATR face, the detector face, and the high-reflectance face are all coplanar. An array detector is fixedly attached to the prism proximate the detector face to sense an internal position of the internal beam and an intensity of the internal beam for each reflection of the internal beam off the detector face.

摘要： An optical system optically characterizes a sample. The optical system includes an incident optical path, extending from a light source to the sample, and a return optical path, extending from the sample to a detector. The optical system assigns unique frequencies to lateral locations on the sample, modulates light for each lateral location at the corresponding assigned frequency, and spectrally analyzes electrical signals produced by pixels at the detector to determine how much light from a particular lateral location at the sample is present at each detector pixel. In some configurations, the system can detect confocally by performing modulation twice, in two of the following four locations: at the light source, in the incident optical path at a modulator between the light source and the sample, in the return optical path at a modulator between the sample and the detector, or at the detector.

摘要： A prism is configured to receive a collimated beam and propagate an internal beam that follows a path inside the prism. The path inside the prism reflects off a first detector face of the prism, then reflects off an ATR face of the prism, then arrives at a second detector face of the prism. First and second array detectors are attached in fixed relation to the prism proximate the first and second detector faces, respectively, to sense an internal position of the internal beam and an intensity of the internal beam for each reflection of the internal beam off the detector face.

摘要： Optical element (300) including a substrate (306) having an interface onto which a coating (310) is disposed. The thickness (in microns) of the coating (310) is greater than 0.03 and smaller than 0.6 / N where N denotes the refractive index of said coating at a wavelength of 12 microns. The substrate may be formed of germanium (Ge) or of a chalcogenide glass (including e.g. Se, As, Sn, S or Te). Materials suitable for the coating include silicon carbide (SiC), boron nitride (BN), alumina (AI2O3), diamond-like carbon (C), or chemical vapor deposition diamond. The coating can be a single, monolithic layer but shall be thin enough to significantly affect the optical reflectivity at the interface surface between the substrate and a sample and be thick enough to both physically and chemically protect the substrate.

摘要： A device and method for measuring a reflectivity of a sample at a plurality of discrete, predefined incident angles. The device includes a sample interface that simultaneously spans across measurement faces of multiple waveguides. Each waveguide is associated with a respective, single incident angle. At least two of the incident angles are different. In some cases, the incident angles are invariant for each waveguide and vary from waveguide to waveguide. In some examples, the device includes a broadband light source and at least one spectral filter. For configurations in which a particular waveguide performs measurements at more than one wavelength, the device includes a spectral filter for each wavelength, which are switchable into and out of the optical path. In some examples, the waveguide geometry determines the incident angle on the sample, and the geometry varies from waveguide to waveguide.

摘要： A spectrometer can optically characterize a sample. An illuminator/collector directs light onto the sample at one of a plurality of wavelengths and, optionally, one of a plurality of incident angles, and collects light from the sample. A detector converts the collected light to an electrical signal. For a typical scan of a sample, a computer can switch off the incident light between sample measurements, during which the computer can adjust the incident angle and/or the wavelength of the incident light. During the times that the incident light is on, the computer can take measurements of the sample, known as light levels. During the times that the incident light is switched off, the computer can take measurements of ambient light, known as dark levels. The computer can use ongoing dark level measurements to perform dynamic correction for ambient light.
