Abstract: A device according to the present invention includes an interferometer which produces interference fringes from light received from a light source. The interference fringes are imaged onto a photo-diode array which transforms the imaged interference fringes into a single set of electric signals. The single set of electric signals is digitized and stored as a group of consecutive data points which represent an interferogram signal containing a DC component. The data points are processed to obtain moving average values representing the DC component of the interferogram signal. The moving average values are subtracted from the data points to obtain a clean interferogram signal which is Fourier-transformed to obtain a spectrogram of the light source.

Abstract: A laser referencing system is disclosed which is used in a refractively scanning interferometer. The interferometer optics comprise a fixed wedge-shaped prism having a beamsplitter surface, a movable wedge-shaped prism, and two corner cube reflectors. A laser clocking beam enters the interferometer on a path below the infrared analytical beam, and leaves the interferometer on a path above the infrared beam. Quadrature control of the laser beams is used to control the ends of the scanning sweeps, eliminating the need for a third, "white light" interferometer beam. ZPD alignment is accomplished by horizontal adjustment of the fixed beamsplitter prism. The interferometer optics are supported three-dimensionally in a cast shell.

Abstract: An interferometer is disclosed, preferably of the Michelson type, in which the reflectors associated with the interferometer arms are stationary, and scanning is accomplished by motion of a wedge-shaped refractive element in one of the arms, the orientation of the refractive element and its direction of motion being in specific mathematically derived directions which minimize the translatory displacement of the transmitted optical beam.
