Light pulse intensity regenerator, light tranforming repeater, pre-amplifier for light signal, light intensity change measuring apparatus, and stabilized light source
First Claim
1. A light pulse intensity regenerating apparatus comprising:
- separating means for separating incident light into a first beam and a second beam;
light detecting means for receiving said first beam from said separating means;
a light amplifying section for amplifying the second beam from said separating means in accordance with an amplitude of an electric signal output from said light detecting means;
a light deflecting section for deflecting the second beam in accordance with an amplitude of an electric signal output from said light detecting means; and
light limiting means for permitting only light having a deflection angle within a predetermined range out of output light from said light deflecting section to pass therethrough;
wherein control timings of said light amplifying section and of said light deflection section are adjusted with the electric signal from said light detecting means such that an amplification amount in said light amplifying section and a deflection amount in said light deflecting section reflect an intensity of light passing through said light amplifying section and an intensity of light through said light deflecting sections respectively.

Abstract
Input light incident into fiber end is separated by a light separator. Light traveling straight through the light separator is guided through an optical fiber to a light amplifying and deflecting section, where only components with deflection angle in a predetermined range are amplified and deflected then to be extracted. The extracted components are output as output light through an optical fiber. The other part of light separated by the light separator is received by a photo detector. The light received by the photo detector is converted into an electric signal, and the electric signal is then input into the light amplifying and deflecting section. Using the electric signal generated from the photo detector, desired wave shaping may be effected by adjusting a light amplification factor of the light amplifying and deflecting section, a change speed of deflection angle, and/or a range of deflection angle selected.
