A kind of precision harmonic gear drive in the focusing mechanism of space camera is studied
which adopt external meshing complex wave transmission mode. Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion
and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio
high precision
compact structure
high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera
the location relationship between the displacement of focusing structure and the focal plane movement is derived
and the system error is analyzed
its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70
repeated positional accuracy is 2m
which meet the requirements for use. 2010 SPIE.

Photolithography shutter is usually used to control exposure in order to obtain patterns of code disc and metrology grating which are the core components of optical shaft encoder. But perforated film as photolithography shutter has many disadvantages such as taking too long time to perforate
easily making wrong code
lower reusable ratio. Mathematical models for resist property
luminous efficiency and exposure have been established by deducing their relations for avoiding the disadvantages
which provides the theory of using liquid crystal light valve (LCLV) replacing proforated film. Based on operating principles of LCLV and control theories of photolithography shutter
the principle diagram of control circuit of LCLV arrays has been designed according to theirs control principles. In the control system
LCLV arrays as photolithography shutter are realized by adopting DS75451 to drive them and using AT89C51 chip to control them. By photolithographic experiment
the patterns of code disc are good
the edges of lines are vertical
it indicates LCLV arrays as photolithography shutter may control exposure and light passing accords with the intending requires. It proves using LCLV arrays replacing perforated film as photolithography shutter is feasible completely.
