1. A microorganism detection apparatus comprising:
a body;
a sample accommodator module provided in the body to accommodate a sample;
a beam irradiation module for irradiating a beam to the sample;
a sensor module for detecting speckles generated when the beam irradiated to the sample is scattered due to motion of bacteria or microorganisms comprised in the sample; and
a controller for controlling the beam irradiated from the beam irradiation module, and storing and analyzing images detected by the sensor module;
wherein the sample accommodator module comprises:
a sample accommodation block having a sample hole capable of accommodating a container containing the sample; and
a heater for supplying heat to the bacteria or microorganisms in the sample at a preset temperature,
wherein the sample accommodation block is made of aluminum, and
wherein the sample accommodation block comprises:
a block body;
a first block surrounding at least a portion of the block body;
a second block surrounding at least another portion of the block body;
an irradiator accommodator provided at a side of the sample accommodation block and connected to the sample hole to accommodate at least a portion of the beam irradiation module;
an image detector provided at another side of the sample accommodation block and connected to the sample hole to allow the sensor module to detect an image scattered by the sample, and
wherein the irradiator accommodator comprises:
a first irradiator hole provided in a side surface of the block body in a hole shape into which an end of the beam irradiation module is inserted;
a second irradiator hole provided at a side of the first block to surround a lower side of a portion of the beam irradiation module; and
a third irradiator hole provided at a side of the second block to correspond to the second irradiator hole and surround an upper side of the portion of the beam irradiation module.
