Fertility analyzer
First Claim
1. Fertility analyzer, comprisinga) means for emitting a laser beam adapted to impinge on a sperm sample in a capillary having a substantially circular section,b) a first optical means including at least a first lens means focusing said laser beam in said sample,c) a second optical means including at least a second lens means, a first diaphragm means determining the area of said sample to be monitored, a second diaphragm means determining the space angle of the scattered light from said sample, and a light intensity detecting means,d) a separating means included in the combination of said first and second optical means for sorting out a determinable small section of said beam outgoing from said sperm sample in a direction lying in a plane having space symmetry in relation to said capillary, and being displaceable to at least two predetermined positions along a straight path of movement in order to sort out said beam in one direction at a time, ande) a signal processing device storing the varying signals from said light detecting means during a predetermined time separately for beams outgoing from said sperm sample in at least two chosen directions, one said beam in one direction at a time, and for computing at least two parameters related to the fertility of the sperm sample.

Abstract
A fertility analyzer includes a laser beam impinging on a sperm sample in a capiliary, a first optical system including at least a first lens focusing the laser beam in the sample, and a second optical system including at least a second lens, a first diaphragm determining the volume element of the sample to be monitored, a second diaphragm determining the space angle of scattered light and a light intensity detecter. A signal processing device stores the signals from the light detector during a predetermined time separately for beams outgoing from the sperm sample in at least two chosen directions and computes at least two features having relation to the fertility of the sperm sample. A separator included in the combination of the first and second optical systems sorts out a determinable small section of the beam outgoing from the sperm sample in a direction lying in a plane approximately parallel to a plane including the capillary.
