摘要： A multifrequency laser oscillator which generates coherent light of two closely adjacent optical frequencies in rapid succession for recording contour holograms by the double exposure technique. The two light frequencies are selected by a pair of frequency selecting reflectors at one end of the oscillator resonator cavity. At least one of these reflectors is movable between an active position where it reflects the laser beam to select one light frequency and an inactive position where the other reflector reflects the beam to select the other light frequency. The described laser oscillators have a ruby lasing medium and generate coherent light at the R1 and R2 wave lengths of the ruby resonant fluorescence.

摘要： A HOLOGRAPHIC SYSTEM FOR RECORDING MULTIPLE-EXPOSURE HOLOGRAMS. THE HOLOGRAMS ARE TAKEN BY A PULSED LASER AND EACH RESPECTIVE REFERENCE BEAM IS DEFLECTED SO THAT IT REACHED THE RECORDING MATERIAL AT A PLURALITY OF DISCRETE DIFFERENT ANGLES. EACH OF THE MULTIPLE-EXPOSURE RECORDINGS OF THE HOLOGRAM MAY BE REPRODUCED BY A REFERENCE BEAM HAVING THE SAME ANGLES AS THAT AT WHICH IT WAS TAKEN. THE REFERENCE BEAM MAY, FOR EXAMPLE, BE DEFLECTED BY UTILIZING AN ELECTRO-

OPTICAL RETARDER FOLLOWED BY A DIREFRINGENT CRYSTAL FOR DEFLECTING THE BEAM IN ACCORDANCE WITH ITS DIRECTION OF POLARIZATION. THE PATHS OF THE REFERENCE BEAMS FOR EACH DISCRETE ANGLE MAY BE EQUALIZED BY THE PROVISION OF A PLURALITY OF REFLECTORS DISPOSED ALONG AN ELLIPSE HAVING THE RECORDING MATERIAL AND A FIRST REFLECTOR AS ITS FOCAL POINTS.

摘要： A ruby or other solid laser is made to generate two or more closely adjacent optical frequencies. By illuminating an object to be recorded holographically with the laser light, range contours are generated when the hologram is reconstructed. The range contours can be made to have distances on the order of 5 millimeters or more by utilizing a ruby laser. To this end, one of the two boundaries of the optical cavity for the laser is formed by a suitable mode selector, such, for example, as a Fabry-Perot resonant reflector, a prism or a grating. The thickness of the resonant reflector is so selected that two or more frequencies may be generated within the lasing linewidth of the laser. Preferably, in order to obtain better contrast, the optical length of the cavity is a multiple of the optical thickness of the resonant reflector. The invention described herein was made in the performance of work under a NASA contract and is subject to the provisions of Section 305 of the National Aeronautics and Space Act of 1958, Public Law 85-568 (72 Stat. 435; 42 U.S.C. 2457).
