Title: Bpsk modulation circuit with flat envelope characteristic
Inventor: BIYONNJIN CHIYON
IPC: H04L27/20
Filed: 1991-10-04
Abstract: PURPOSE: To prevent distortion from a phase transient supporting point at the time of power amplification by uniforming the levels of all the signals including the phase transient supporting point at the time of BPSK modulation. CONSTITUTION: When a system clock (a) is inputted to a data generating means 10, the means 10 divides 110 the frequency of clock (a) and generates random data synchronously with this clock later. While receiving the output of data generating means 10, a data converting means 20 outputs an in-phase signal I(t) in the form of reception stage to be made alternative synchronously with the clock (a) and a cut phase signal Q(t) to be uni-directionally repeated to a modulating means 30. While receiving a carrier wave signal from a carrier wave oscillator 170, the modulating means 30 performs double bounced modulation to a carrier wave concerning the signal I(t) and performs the single bounce modulation of signal transiting the phase of carrier wave concerning the signal Q(t). An adder 210 adds both the signals and provides the BPSK modulated signal having flat envelope characteristics.

IPC: G01M11/02
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating optical image forming element by which the transferability of the optical surface of an image forming element can be evaluated without damaging the element. SOLUTION: A reference beam is made incident on a roof prism lens 3 from the incident-side surface 4 of the lens 3 by using a Fizeau optical interferometer 21 and, after the beam is reflected by two surfaces of a roof prism 9, the beam is condensed onto the image forming-side surface 5 of the lens 3.
