Title: Improvements in or relating to automatic filter spectographs
IPC: G01J3/28
Filed: 1957-12-09
Abstract: 876,094. Spectral display apparatus. PRETEMA A. G. Dec. 9, 1957 [Dec. 12, 1956], No. 38237/57. Class 40(3) [Also in Grou p XX] In a spectral display apparatus in which a series of filters mounted at the periphery of a scanning disc are rotated through a beam of radiation being analyzed, the radiation transmitted by the filters is converted to electrical signals and displayed on a cathode ray tube. The filter transmission ranges are chosen so that one revolution of the disc corresponds to a single passage through the spectral range which is being investigated. Light emitted by, reflected from or transmitted by the object under that is callimated in unit 1 and passed via filter units 2a and an optical system 3 to a radiation receiver 4. The filter units 2a, which are mounted on the scanning disc 2 driven by a motor 6, each comprises an interference filter of narrow band width, a diaphragm arranged to alter the filter sensitivity and means for further altering this sensitivity by the addition of a grey filter. The signals produced by the radiation receiver may be directly displayed on a C.R.T. 10 which has horizontal tine base synchronized in unit 11 to the speed of rotation of the securing disc. The signals may also be applied to the C.R.T. via a switching arrangement which includes commutator type switches 7 and 9 driven by the motor 6. Each switch is provided with segments corresponding in number and position to the filter units mounted on the scanning disc and by this means the sensitivity of the apparatus can be further adjusted by providing a separate adjustable load resistance for the radiation receiver for each filter position. By the choice of suitable load resistances the sensitivity of the apparatus may be set to that of the human eye or other simulation curve. Unit 13 and commutator type switch 14 apply compensating voltages in each filter position to cancel the voltages produced by disturbing line spectra when performing combined spectra analysis and the integral of the received pulses can be obtained in circuit 12.
