Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A method for measuring an angle of incidence for short pulses of speckled radiation, caused by a turbulent atmosphere, in relation to a reference direction, comprising the steps of: mounting two detector elements so each detector element receives essentially the same irradiance and in such a direction that the normals of each respective detector element form a known angle with each other; and calculating the angle of incidence using signals from the detector elements, depending on the shape of the sensitivity beams, and said known angle between the detector elements.
Claim 2
Independent Claim
90 words
A method for measuring an angle of incidence for short pulses of speckled radiation, caused by a turbulent atmosphere, in relation to a reference direction, comprising the steps of: mounting two detector elements so each detector element receives essentially the same irradiance and in such a direction that the normals of each respective detector element form a known angle with each other; and calculating the angle of incidence using signals from the detector elements, depending on the shape of the sensitivity beams, and said known angle between the detector elements.
Claim 3
Dependent Claim
29 words
A method according to claim 1 wherein mounting the detector elements in said mounting step is performed so the correlation between their respective measured irradiance is greater than 0.9.
Claim 4
Dependent Claim
34 words
A method according to claim 1 further comprising the steps of: choosing rectangular detector elements; and mounting the detector elements with their long sides against each other giving a small average distance between them.
Claim 5
Dependent Claim
111 words
A detector for measuring the angle of incidence for short pulses of speckled radiation caused by a turbulent atmosphere in relation to a reference direction comprising: a first detector element; and a second detector element mounted to said first detector element so said first and second detector elements receive essentially the same irradiance and are orientated to have the normals of each respective detector element form a known angle with each other, wherein the angle of incidence can be calculated by means of signals from the first and second detector elements, that depend on the shape of the sensitivity beams, and said known angle between the first and second detector elements.
Claim 6
Dependent Claim
111 words
A detector for measuring the angle of incidence for short pulses of speckled radiation caused by a turbulent atmosphere in relation to a reference direction comprising: a first detector element; and a second detector element mounted to said first detector element so said first and second detector elements receive essentially the same irradiance and are orientated to have the normals of each respective detector element form a known angle with each other, wherein the angle of incidence can be calculated by means of signals from the first and second detector elements, that depend on the shape of the sensitivity beams, and said known angle between the first and second detector elements.
Claim 7
Dependent Claim
27 words
A detector according to claim 4 wherein the first and second detector elements are mounted so the correlation between their respective measured irradiance is greater than 0.9.
Claim 8
Dependent Claim
32 words
A detector according to claim 4 wherein the first and second detector elements are rectangular and mounted with their long sides against each other to give a small average distance between them.
