Abstract: An optical detection device includes a first linear light source, a second linear light source, an optical sensor array and a processor. The first linear light source is adapted to project a first long strip illumination beam onto the target container. The second linear light source is adapted to project a second long strip illumination beam onto the target container, and the second long strip illumination beam is crossed with the first long strip illumination beam. The optical sensor array is adapted to receive a first long strip detection beam and a second long strip detection beam reflected from the target container. The processor is electrically connected to the optical sensor array. The processor is adapted to analyze intensity distribution of the first long strip detection beam and the second long strip detection beam to acquire a relative distance between the optical sensor array and the target container.

Abstract: An optical detecting module includes a housing, a light emitting component, an optical detecting component and an optical signal collecting component. The light emitting component is disposed inside the housing. The optical detecting component is disposed inside the housing to receive an optical detecting signal generated by the light emitting component. The optical signal collecting component is utilized to hold the light emitting component for signal collection. The optical signal collecting component includes an output portion, a bottom portion and at least one lateral portion. The light emitting component is disposed on the bottom portion, and an optical positive signal of the optical detecting signal is projected out of the housing through the output portion. The lateral portion is bent from the bottom portion to reflect an optical lateral signal of the optical detecting signal, and the optical lateral signal is projected out of the housing through the output portion.
