Abstract: Method for calibrating a spectral imaging device comprises forming first calibration light by illuminating a first calibration region of a calibration sample with illuminating light, forming second calibration light by illuminating a second calibration region of the calibration sample with the illuminating light, measuring a first spectrum of the first calibration light by using the spectral imaging device, measuring a second spectrum of the second calibration light by using the spectral imaging device, and determining or verifying a spectral calibration function of the spectral imaging device by comparing the measured spectra with reference spectra. The spectral calibration function specifies a relation, which associates values of a control parameter with actual spectral positions. The first calibration light has a first spectral peak at a first peak wavelength, and the second calibration light has a second spectral peak at a second peak wavelength.

Abstract: Optical systems have uses, such as in spectrometers, for directing a beam. A spectrometer, for example, utilizes an optical system for directing an incident beam toward a sample and receiving a spectroscopy signal from the sample. In various implementations, for example, an optical system may be further configured to move a beam with respect to a target, such as a sample, and still provide a home position where the beam is directed in a stationary configuration. A self-homing (e.g., self-centering) optical system may provide a “home” position in which the beam is directed in a first stationary mode while still allowing a focused beam to be moved with respect to a target in a second dynamic mode.

Abstract: According to some embodiments, a Micro Wideband Spectroscopic Analysis Device (MWSAD) is designed to operate from the visible to the far infrared. The MWSAD is the first unified platform to implement nearly all kind of molecular spectroscopy. This design is based on combining/integrating Diffractive Focusing Element (DFE) such as Fresnel lens/Zone plate with wide and finite range tuning devices. The wide range tuning devices are tunable lenses and/or a long stroke linear motor. The finite tuning devices are micro pinhole controlled by MEMS/PZT actuator. The MEMS/PZT actuator is used for finite tuning the micro pinhole location across the chromatic focuses of the Fresnel lens/DFE. The long stroke linear motor is used for wide range tuning the pinhole location across the chromatics focuses. The tunable lens is used for wideband tuning the chromatics focuses locations within the micro pinhole.
