An optical apparatus comprises a fixing base; a plurality of light emitting units and a plurality of holders. The light emitting units emits a plurality of light beams and each light emitting unit has a holding portion. Each holder has an accommodating indentation for accommodating the corresponding light emitting unit. The accommodating indentation exposes the holding portion of the corresponding light emitting unit so that a jig holds the exposed holding portion and adjusts the position of the holder and the light emitting unit before the holder is fixed to the fixing base and then adjusts the position of the light emitting unit within the holder after the holder is fixed to the fixing base. And then the light emitting unit is fixed to the holder.

Optical apparatus having light sources and a plurality of holders for holding the light sources

An optical module used in a projection device is provided. The optical module includes a base and a filter mirror. The base has an inclined leaning surface and a sidewall surface. The sidewall surface is located at a periphery of the base and forms a through hole along a direction. The inclined leaning surface is extended from the sidewall surface and an inclined angle is formed between the inclined leaning surface and the direction. The filter mirror is disposed on the inclined leaning surface.

Optical module used in projection device

A laser projection system comprising a laser light and a human body detection module is disclosed. The laser light source emits a laser light. The human body detection module detects a reflective light of the laser light irradiated on an object. The human body detection module determines whether the object is a human according to a relationship between several reflectivity indexes of the reflective light. If the relationship corresponds to predefined situation, the human body detection module reduces a laser output intensity of the laser light.
