Description
Technical field
The utility model belongs to face battle array photoelectric auto-collimation field of measuring technique, is specifically related to a kind of array image sensor position of focal plane adjusting mechanism.
Background technology
Area array CCD/CMOS photoelectric auto-collimator is in recent years along with a kind of angle measurement instrument that the development of semiconductor technology newly produces.Photoelectric auto-collimator is gathered angle defection signal by imageing sensor, has Automatic survey, precision advantages of higher, but need solve following problem when face battle array photoelectric direct collimator is debug:
1. the judgement that whether puts in place of imageing sensor position of focal plane.Photoelectric direct collimator is launched by self light source, after target reflection, turn back to optical system enters on optical sensitive device CCD/CMOS, when position of focal plane is not in focus, imaging can be empty, acutance is inadequate, edge, also by fuzzy, can not ensure measuring accuracy, therefore needs one can judge the method for imageing sensor whether on focal plane.
2. the mechanism of position of image sensor adjustment can be realized.Imageing sensor is installed on pedestal, when judging that imageing sensor not rationally, needs imageing sensor can be convenient to adjustment.
At present, the relevant report about pin imageing sensor position of focal plane, face method of adjustment is not yet had.Installation for face pin imageing sensor is also extensively referred from Linear Array CCD Image Sensor Method of Adjustment, the method measures the voltage signal of CCD output, oscillograph is utilized to observe CCD measurement signal voltages waveform, the method is comparatively ripe, be applicable to the occasion directly can measuring bottom hardware signal, but for face formation imageing sensor, be many times to measure bottom layer signal, the method cannot be suitable for; Another method is exactly rely on machining completely, in strict accordance with ideal dimensions making image sensor holder, no longer will adjust, but due to mismachining tolerance, ensure that position of focal plane is completely reasonable, possibility hardly, therefore the method is also difficult to realize.
Summary of the invention
The purpose of this utility model be to solve prior art cannot array image sensor in Installation and Debugging time adjust the problem of position of focal plane easily and effectively, a kind of array image sensor position of focal plane adjusting mechanism is provided.
The utility model is achieved in that
