Abstract:
A method for projecting light onto a subject in an imaging system, the method comprising:providing a light source operable to project light in pulses; providing a pixel panel to selectively direct the projected light towards the subject; determining at least a first period and a second period during which the pixel panel directs the projected light towards the subject, the first and second periods each having a start time; during the first period, projecting the light in at least one pulse towards the pixel panel at a first begin time relative to the start of the first period and halting the projection of light at a first end time relative to the start of the first period; during the second period, projecting the light in at least one pulse towards the pixel panel at a second begin time relative to the start of the second period and halting the projection of light at a second end time relative to the start of the second period; and determining an interval between the first end time and the second begin time wherein the interval duration is variable and wherein the first and second begin times are not synchronized relative to the start times of the first and second periods.
