Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A method of focusing spectral energy distribution which comprises: a. directing incident radiation from a source through an aperture; b. dispersing said radiation by passing said radiation through a prism face; c. receiving the dispersed radiation on an echelle grating; d. reflecting said radiation as horizontal and vertical components; and e. focusing the horizontal and vertical components of the radiation at an exit focal plane by: i. rotating the grating about a first axis, said first axis substantially parallel to the prism face; and ii. rotating the grating about a second axis, said second axis substantially normal to the first axis and parallel to the grating rulings.
Claim 2
Independent Claim
107 words
A method of focusing spectral energy distribution which comprises: a. directing incident radiation from a source through an aperture; b. dispersing said radiation by passing said radiation through a prism face; c. receiving the dispersed radiation on an echelle grating; d. reflecting said radiation as horizontal and vertical components; and e. focusing the horizontal and vertical components of the radiation at an exit focal plane by: i. rotating the grating about a first axis, said first axis substantially parallel to the prism face; and ii. rotating the grating about a second axis, said second axis substantially normal to the first axis and parallel to the grating rulings.
Claim 3
Dependent Claim
27 words
The method of claim 1 which includes receiving the radiation from the aperture on a collimating mirror and subsequently reflecting said radiation prior to dispersing said radiation.
Claim 4
Dependent Claim
49 words
rotating the grating about a second axis, said second axis substantially normal to the first axis and parallel to the grating rulings; and h. passing the horizontal and vertical components from the grating through the prism and subsequently focusing said horizontal and vertical components at the exit focal plane.
Claim 5
Dependent Claim
49 words
rotating the grating about a second axis, said second axis substantially normal to the first axis and parallel to the grating rulings; and h. passing the horizontal and vertical components from the grating through the prism and subsequently focusing said horizontal and vertical components at the exit focal plane.
Claim 6
Dependent Claim
29 words
The method of claim 1 which includes dispersing the horizontal and vertical components from the grating and subsequently focusing said horizontal and vertical components at the exit focal plane.
Claim 7
Dependent Claim
27 words
The method of claim 3 which includes receiving the horizontal and vertical components on a collimating mirror and subsequently focusing said components at the exit focal plane.
Claim 8
Dependent Claim
13 words
The method of claim 1 which includes forming a multiplicity of focal planes.
Claim 9
Dependent Claim
15 words
THe method of claim 1 which includes detecting the radiation in said exit focal plane.
Claim 10
Independent Claim
91 words
A method for focusing spectral energy distribution which comprises: a. directing incident radiation from a source through an aperture; b. receiving the radiation from the aperture on a collimating mirror and subsequently reflecting said radiation; c. impinging the radiation on a prism face; d. dispersing said radiation by passing said radiation through the prism; e. receiving the dispersed radiation from the prism on an echelle grating; f. reflecting said radiation as horizontal and vertical components; g. varying the horizontal and vertical components of the radiation at an exit focal plane by:
