1. A microbial detection apparatus comprising:
a body;
a sample receiver formed in the body and comprising a sample receiving block that accommodates a sample;
a light emitter configured to emit light to the sample;
a sensor module configured to detect a speckle generated when the light emitted to the sample is scattered by motion of bacteria or microbes contained in the sample; and
a controller configured to control the light emitted to the sample by the light emitter and store and analyze images detected by the sensor module,
wherein the sample receiving block is surface-treated to remove unevenness of a surface of the sample groove portion and form a pattern on the surface of the sample groove portion so that the light scattered by the sample accommodated in the sample groove portion is uniformly reflected on the surface of the sample groove portion,
wherein the sample receiving block comprises a light emitter receiving portion which is formed on one side of the sample receiving block to accommodate at least a portion of the light emitter and comprising a light emitter groove portion that communicates with the sample groove portion; and
an image detecting portion which is formed on the other side of the sample receiving block so that an image scattered by the sample is detected by the sensor module and comprising
a detection groove portion that communicates with the sample groove portion
wherein the sample groove portion accommodates a container in which the sample is contained and the container is formed overall in the shape of a column having an opening formed on an upper side and a bottom surface formed on a lower side, wherein a light-incident portion that corresponds to the light emitter and a light exit portion that corresponds to the sensor module are formed such that they are not aligned with each other, so that the speckle generated by the light emission module and detected by the sensor module can be amplified.
