| Abstract: | A new type of laser photoelectric calculagraph has beendesigned and constructed.Using this home-made calculagraph to measure the acceleration of gravity in the free-fall experiments,we have a much better accuracy than before.The results show such photoelectric calculagraph has the advom tages of accurate orientation and strong interference rejection etc. |

| Keywords: | free-fall acceleration of gravity photoelectric sensor. |
