Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
An optical streak camera for measuring an input temporal signal beam of light, said optical streak camera comprising: a. means for collimating said input temporal signal beam of light to be measured, b. a first all optical deflector for receiving the collimated input temporal signal and converting the input temporal signal beam of light into a spatial signal beam of light, wherein the first all optical deflector comprises a body of nonlinear optical material and an area modulated, time-dependent, intensity-modulated pump beam of light for producing a time-dependent induced refractive index change in the body of nonlinear material, said induced refractive index change causing a sweeping of said collimated input temporal signal beam of light, c. a detector for detecting the spatial signal beam of light, and d. a display for displaying the spatial signal beam of light.
Claim 2
Dependent Claim
138 words
An optical streak camera for measuring an input temporal signal beam of light, said optical streak camera comprising: a. means for collimating said input temporal signal beam of light to be measured, b. a first all optical deflector for receiving the collimated input temporal signal and converting the input temporal signal beam of light into a spatial signal beam of light, wherein the first all optical deflector comprises a body of nonlinear optical material and an area modulated, time-dependent, intensity-modulated pump beam of light for producing a time-dependent induced refractive index change in the body of nonlinear material, said induced refractive index change causing a sweeping of said collimated input temporal signal beam of light, c. a detector for detecting the spatial signal beam of light, and d. a display for displaying the spatial signal beam of light.
Claim 3
Dependent Claim
24 words
The optical streak camera of claim 1 wherein said area modulated pump beam of light is shaped to include at least one triangular pulse.
Claim 4
Dependent Claim
19 words
The optical streak camera of claim 1 wherein said area modulated pump beam comprises tooth comb shaped optical pulses.
Claim 5
Dependent Claim
23 words
The optical streak camera of claim 1 and further including a second all optical deflector in series with the first all optical deflector.
Claim 6
Dependent Claim
25 words
The optical streak camera of claim 1 wherein the optical nonlinear material has a response time faster than the pulse duration of the pump pulse.
Claim 7
Dependent Claim
25 words
The optical streak camera of claim 1 wherein the optical nonlinear material has a response time slower than the pulse duration of the pump pulse.
Claim 8
Dependent Claim
137 words
An optical streak camera for displaying an input temporal signal beam of light, said optical streak camera comprising: a. means for collimating said input temporal signal beam of light to be measured, b. a first all optical deflector for receiving the collimated input temporal signal beam and sweeping the input temporal signal beam of light into a spatial signal beam of light, said all optical deflector including a non-linear material and a beam of continuous pump pulses, the intensity of said continuous pump pulses being modulated over time to vary the index of refraction of the non-linear material to enable sweeping, c. a detector for detecting the spatial signal beam of light, and d. a display for displaying the spatial signal beam of light, e. the frequency of the display matching the frequency of the pump pulses.
Claim 9
Dependent Claim
137 words
An optical streak camera for displaying an input temporal signal beam of light, said optical streak camera comprising: a. means for collimating said input temporal signal beam of light to be measured, b. a first all optical deflector for receiving the collimated input temporal signal beam and sweeping the input temporal signal beam of light into a spatial signal beam of light, said all optical deflector including a non-linear material and a beam of continuous pump pulses, the intensity of said continuous pump pulses being modulated over time to vary the index of refraction of the non-linear material to enable sweeping, c. a detector for detecting the spatial signal beam of light, and d. a display for displaying the spatial signal beam of light, e. the frequency of the display matching the frequency of the pump pulses.
