<p>PCT No. PCT/SE90/00527 Sec. 371 Date Feb. 6, 1992 Sec. 102(e) Date Feb. 6, 1992 PCT Filed Aug. 15, 1990 PCT Pub. No. WO91/02960 PCT Pub. Date Mar. 7, 1991A method and an apparatus for sectioning a specimen (9) by whereas the apparatus is a microtome. The microtome has at least one optical and one additional sensor (35-37) used for generating signals, the value of which is a measure of the sectioning function. At least one essential sectioning parameter, such as the clearance angle of the knife and/or the sectioning speed, is varied. On the basis of the signal values received, the sectioning parameters concerned are set for optimising the sectioning function. The optical sensor (37) senses greyness and/or surface structure of the sections produced. The other sensors are used e.g. for sensing sound (sensor 35) dependent on the sectioning force or work, or stresses in the knife of the microtome (sensor 36) that are dependent on the sectioning force or work.</p> |
