First Claim
1. Apparatus for the spectroscopic analysis of a specimen, comprising:
- first means for scanning the specimen with a narrow band of a monochromatic light over a range of wavelengths;
second means for scanning the light reflected from said specimen and generating a signal representative thereof;
means for selectively gating a portion of said signal;
means for converting the gated signal into a digital signal;
means for storing said digital signal;
means for storing digital data representative of selected spectroscopic characteristics; and
means for reading out said digital data and said spectroscopic data to identify the spectroscopic characteristics of said specimen.

Abstract
Method and apparatus for the spectroscopic analysis of a specimen in which the specimen is irradiated with a narrow band of monochromatic light over a range of wavelengths, the light reflected from the specimen is scanned to generate a signal representative thereof, the signal is converted into a digital signal and stored. Digital data representative of selected spectroscopic characteristics is also stored and the digital data and the spectroscopic data are read out to identify the spectroscopic characteristics of the specimen. A TV camera scanner enables selective gating by varying the respective horizontal and vertical portions of the video signal. The video signal may be visually monitored to alter the scanning of the specimen and to determine those portions of the signal to be gated.
