Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
An image scanning and display system comprising mechanical-optical means (12-36) for scanning across a field of view and including a detector (30), scan sync pulse generating means (line 56, from 20), and electronic display means (38,40) fed from the detector (30) and with the scan sync pulse (line 88), and stabilizing means for stabilizing the system against instability of the mechanical-optical means, characterized in that the stabilizing means (Figure 2) comprise movement detecting means (GH, 45) for detecting movement of the optical means in the scan direction (horizontal), and circuitry (50-54, 78) for adjusting the timing of the scan sync pulses accordingly.
Claim 2
Dependent Claim

An image scanning and display system comprising mechanical-optical means (12-36) for scanning across a field of view and including a detector (30), scan sync pulse generating means (line 56, from 20), and electronic display means (38,40) fed from the detector (30) and with the scan sync pulse (line 88), and stabilizing means for stabilizing the system against instability of the mechanical-optical means, characterized in that the stabilizing means (Figure 2) comprise movement detecting means (GH, 45) for detecting movement of the optical means in the scan direction (horizontal), and circuitry (50-54, 78) for adjusting the timing of the scan sync pulses accordingly.
Claim 3
Dependent Claim
48 words
A system according to Claim 1, characterized in that said circuitry comprises a phase-locked loop comprising a phase detector (50) fed with the incoming sync pulses and a voltage controlled oscillator (54) fed from the phase detector and from the movement detecting means and feeding the phase detector.
Claim 4
Independent Claim
68 words
A system according to either previous Claim, characterized in that the mechanical-optical system also includes transverse scan means (24,26) for scanning transversely to the scan across the field of view, and the stabilizing means includes movement detecting means (GV,41) for detecting movement.,of the optical means in the transverse direction and which produce a correction signal which is used to adjust the drive signal of the transverse scan means.
