9. the control lamp motion as described in any one in claim 2 to 4 expands the device of areas imaging, and its feature exists
In the driving gear and the driven gear are straight-tooth gear.
10. a kind of ophthalmology OCT systems, including：Light source, spectral module, reference arm module, sample arm module, detecting module and place
Reason module；The light that the light source sends is transferred to the spectral module, and the light that the spectral module will be received is divided into two beams simultaneously
The reference arm module and the sample arm module are respectively supplied to, wherein light beam is transferred to the reference arm module, described
The light that reference arm module will be received is passed back in the spectral module form reference light；Another light beam is through the sample arm mould
Incident eyes after block, form flashlight and are back to the spectral module after being scattered through eyeground, the flashlight and the reference
Light forms interference light after interfering, the detecting module is received after the interference light and transmits it to the processing module,
The processing module processes the interference light, obtains the eye fundus image of tested eyes, it is characterised in that：The light source is placed in such as power
Profit is required in the device of the control lamp motion expansion areas imaging any one of 1-4.
