Abstract
An optical sensing device is provided. The optical sensing device includes a first optical sensor and a filter layer. The first optical sensor is configured to receive a first optical signal. The filter layer covers the first optical sensor, and is configured to filter out the first optical signal when the first optical signal is incident on the filter layer at an incident angle not within a specific range.
Claims13
An optical sensing device comprising:
- a first optical sensor, configured to receive a first optical signal;
- and
- a filter layer, wherein the filter layer covers the first optical sensor and is configured to filter out the first optical signal when the first optical is incident on the filter layer at an incident angle not within a specific range.
An optical sensing module, comprising:
- a circuit board;
- a light source, displaced on the circuit board, wherein the light source is configured to emit a first optical signal;
- and
- an optical sensing device, displaced on the circuit board, wherein the optical sensing device comprises:
- a first optical sensor, configured to sense the first optical signal reflected by an object to be sensed;
- and
- a filter layer, wherein the filter layer covers the first optical sensor, and is configured to filter out the first optical signal when the first optical signal is incident on the filter layer at an incident angle not within a specific range.
